How to Answer
Implement an efficient algorithm for finding the GCD, such as Euclid’s algorithm. Also, don’t forget to handle edge cases, such as empty lists or lists with a single element.
Example
“First, we’ll handle edge cases: if the list is empty, we’ll return None, and if it contains only one element, we’ll return that element. Then, we’ll define a helper function find_gcd based on Euclid’s algorithm to find the GCD of two numbers. Within the main function, we’ll initialize the GCD variable with the first element of the list and iterate through the remaining elements, updating the GCD using the helper function. Finally, we’ll return the computed GCD.”
def gcd(int_list):
if not int_list:
return None
if len(int_list) == 1:
return int_list[0]
def find_gcd(a, b):
while b:
a, b = b, a % b
return a
result = int_list[0]
for i in range(1, len(int_list)):
result = find_gcd(result, int_list[i])
return result
int_list = [8, 16, 24]
print(gcd(int_list)) # Output: 8
7. Can you walk us through your approach to feature selection?
At IBM, data scientists work with large datasets to train machine learning models. Therefore, you need to be able to select relevant features to improve model performance and reduce computational overhead.
How to Answer
Mention the techniques you use for feature selection and considerations for dealing with high-dimensional data. Also, demonstrate your understanding of feature importance, dimensionality reduction methods, and the impact of feature selection on model performance.
Example
“My approach to feature selection involves several steps. First, I explore the dataset and understand the relationships between features and the target variable. Then, I use techniques such as correlation analysis and domain knowledge to identify potentially relevant features.
Next, I apply dimensionality reduction techniques such as principal component analysis (PCA) or feature importance estimation methods like tree-based algorithms to reduce the dimensionality of the dataset while preserving as much relevant information as possible.
Then, I evaluate the model’s performance using the selected features and iteratively refine the feature set based on performance metrics such as accuracy, precision, recall, or F1-score.”
8. How can you write a function compute_deviation that takes in a list of dictionaries with a key and list of integers and returns a dictionary with the standard deviation of each list?
One task you’ll have as a data scientist at IBM is writing the code for a particular statistical concept. With this question, your ability to implement statistical computations without relying on external libraries like NumPy will be tested.
How to Answer
Demonstrate your understanding of the standard deviation formula and provide a function that computes the standard deviation for each list of integers in the input list of dictionaries.
Example
”To compute the standard deviation of each list of integers in the input list of dictionaries, we’ll define a function named compute_deviation.
First, we’ll iterate through each dictionary in the input list, extracting the list of values and computing the mean. Then, we’ll calculate the sum of squared differences from the mean, divide by the number of elements minus one, and take the square root to obtain the standard deviation. We’ll store the results in a dictionary with the corresponding keys and return it. ”
def compute_deviation(input):
output = {}
for item in input:
key = item['key']
values = item['values']
mean = sum(values) / len(values)
squared_diff_sum = sum((x - mean) ** 2 for x in values)
variance = squared_diff_sum / (len(values) - 1)
std_deviation = variance ** 0.5
output[key] = round(std_deviation, 2)
return output
9. Can you explain a complex statistical concept in layman’s terms?
As a data scientist, you need to be able to explain technical concepts clearly. This skill is particularly important at IBM, where you’ll work on a cross-functional team.
How to Answer
Choose an example of a statistical concept and explain it using simple language and everyday examples anyone can understand. Avoid technical jargon and focus on making the concept relatable and easy to grasp.
Example
“Let’s take the concept of p-values, commonly used in hypothesis testing. Imagine you’re a detective trying to solve a crime. The p-value is like the strength of your evidence against a suspect.
If the p-value is low (say, less than 0.05), it means the evidence (or data) you have is quite rare if the null hypothesis (the suspect is innocent) were true. In other words, it suggests that the evidence is strong enough to consider the suspect guilty.
On the other hand, if the p-value is high (greater than 0.05), it means the evidence you have is not very rare if the null hypothesis were true. It’s like finding common fingerprints at the crime scene that could belong to anyone. In this case, you wouldn’t have enough evidence to convict the suspect.”
10. Given two sorted lists, how can you write a function to merge them into one sorted list?
Data scientists at IBM need to possess some fundamental knowledge about data structures and algorithms. Therefore, your ability to solve algorithmic problems and manipulate data structures efficiently will be tested.
How to Answer Implement an algorithm that efficiently combines the two lists while maintaining the sorted order, and discuss the time complexity of your solution.
Example
”To merge two sorted lists into one sorted list, we can iterate through both lists simultaneously, comparing elements and appending them to a new list in sorted order. We’ll start by initializing two pointers at the beginning of each list and compare the elements pointed to by the pointers. The smaller element is appended to the new list, and the corresponding pointer is incremented. We continue this process until we reach the end of either list. If one list still has remaining elements, we append them to the new list. This approach has a time complexity of O(n + m), where n and m are the lengths of the two input lists.”
def merge_lists(list1, list2):
merged_list = []
i, j = 0, 0
while i < len(list1) and j < len(list2):
if list1[i] <= list2[j]:
merged_list.append(list1[i])
i += 1
else:
merged_list.append(list2[j])
j += 1
merged_list.extend(list1[i:])
merged_list.extend(list2[j:])
return merged_list
list1 = [1, 2, 5]
list2 = [2, 4, 6]
print(merge_lists(list1, list2)) # Output: [1, 2, 2, 4, 5, 6]
11. How do you detect outliers in a dataset?
Detecting outliers is an essential step in data cleaning to ensure the quality of your statistical analysis. As you’ll be working with big data at IBM, you must deal with these outliers in each data science project.
How to Answer
Discuss methods commonly used to detect outliers in a dataset, such as z-score, IQR (interquartile range), and visualization techniques. Don’t forget to mention the importance of domain knowledge when determining whether data points are outliers.
Example
“Detecting outliers in a dataset is essential for ensuring the quality and reliability of the data used for analysis and modeling. One common approach is to use statistical methods such as the z-score or IQR (interquartile range) to identify data points that deviate significantly from the mean or median of the dataset. Another approach is to visualize the data using techniques such as box or scatter plots, which can help identify data points that fall outside the expected range of values.
However, domain knowledge and context are important considerations when determining whether a data point is an outlier, as some outliers may be valid data points representing rare events or anomalies in the data.”
12. What are z- and t-tests, and when should one be used over the other?
Hypothesis testing is a common task you’ll perform as a data scientist at IBM. So, understanding the differences between different statistical tests is crucial to ensure the validity of your statistical analysis.
How to Answer
Discuss the purpose of and differences between z- and t-tests. Explain when each test is typically used and under what circumstances we would choose one over the other.
Example
“The z- and t-tests are both statistical tests used to make inferences about population parameters based on sample data. The z-test is typically used when the sample size is large (usually n > 30) or when the population standard deviation is known. It assesses whether the mean of a sample differs significantly from the population mean.
On the other hand, the t-test is used when the sample size is small (usually n < 30) or when the population standard deviation is unknown. It assesses whether the mean of a sample differs significantly from the population mean when the population standard deviation is estimated from the sample.
The key difference between the two tests lies in the assumptions about the population standard deviation: the z-test assumes that the population standard deviation is known, while the t-test does not make this assumption and instead estimates the population standard deviation from the sample.”
13. What is entropy and information gain?
Decision tree is one of the most popular machine learning algorithms due to its performance and interpretability. Since you’ll most likely use this algorithm at IBM, understanding its inner workings is necessary.
How to Answer
Discuss the relevance of entropy and information gain in decision tree algorithms. Explain how entropy measures the impurity in a dataset and how information gain quantifies the effectiveness of a feature in reducing the entropy of the resulting subsets.
Example
“Entropy is a measure of impurity in a dataset. In the context of decision tree algorithms, entropy is used to quantify the uncertainty associated with the classification of data points in a dataset. Higher entropy indicates higher disorder, while lower entropy indicates more homogeneous subsets.
Information gain, on the other hand, measures the effectiveness of a feature in reducing the entropy of the resulting subsets when making split decisions in a decision tree. Features with higher information gain are preferred as they lead to more effective splits, resulting in decision trees that better classify the data.”
14. A team wants to A/B test multiple different changes through a sign-up funnel. They want to see if changing a button from red to blue and/or from the top of the page to the bottom of the page will increase click-through. How would you set up this test?
Since hypothesis testing is a critical topic in data science, expect some study case questions about it during your data scientist interview at IBM.
How to Answer
Outline the steps in setting up an A/B test to evaluate multiple changes in a sign-up funnel. Discuss key considerations such as defining the hypothesis, selecting appropriate metrics, designing variants, determining sample size and duration, and analyzing the results.
Example
”To set up an A/B test for evaluating multiple changes in a sign-up funnel, first I would select appropriate metrics such as click-through rate. Then, I would randomly assign users to each variant to ensure an unbiased comparison between the different changes. Next, I would calculate the necessary sample size to achieve sufficient statistical power and decide on the duration of the experiment to collect enough data.
Finally, by using statistical methods, I would analyze the collected data and determine if any of the changes significantly impact the click-through rate. For this, I would consider factors like statistical significance and confidence intervals.”
15. What do you understand about stochastic gradient descent?
In your interviews to become a data scientist at IBM, expect some questions about general machine learning concepts. Also, gradient descent is a popular optimization method for regression models, which are commonly applied in data science projects at IBM.
How to Answer
Explain stochastic gradient descent by highlighting its importance in training machine learning models and optimizing the model parameters. If possible, also mention practical considerations such as learning rate scheduling and mini-batch sizes commonly used in SGD.
Example
“Stochastic gradient descent (SGD) is an optimization algorithm commonly used in machine learning for training models and optimizing their parameters. Unlike standard gradient descent, which computes the gradient of the loss function using the entire training dataset, SGD updates the model parameters based on the gradient computed on a randomly selected subset of training data, known as a mini-batch. This makes SGD computationally efficient and allows it to handle large-scale datasets.
SGD iteratively updates the model parameters in the direction of the negative gradient of the loss function, aiming to minimize the loss and improve the model’s performance. By updating the parameters incrementally after each mini-batch, SGD gradually converges to a local minimum of the loss function.
Practical considerations such as learning rate scheduling, momentum, and mini-batch sizes play a crucial role in optimizing the performance of SGD and ensuring convergence to an optimal solution.”
16. What is the difference between covariance and correlation?
This question evaluates your knowledge of data analysis and statistics fundamentals. At IBM, you’re expected to know basic statistical concepts and how to apply them in data analysis tasks.
How to Answer
Discuss the difference between covariance and correlation by emphasizing their differences in scale and interpretation.
Example
“Covariance measures the degree to which two variables change together, with positive values indicating a positive relationship and negative values indicating a negative relationship. On the other hand, correlation standardizes covariance by dividing it by the product of the standard deviations of the two variables. This results in a value between -1 and 1, where 1 indicates a perfect positive linear relationship, -1 indicates a perfect negative linear relationship, and 0 indicates no linear relationship.
Unlike covariance, correlation is not influenced by the scale of the variables, making it easier to interpret and compare across different datasets. For example, in analyzing the relationship between temperature and ice cream sales, covariance would show how they change together, while correlation would provide insight into the strength and direction of the relationship, facilitating easier interpretation.”
17. What is the difference between precision and specificity?
This question tests your knowledge of general machine learning concepts. After you develop a machine learning model, you need to know how to assess its performance. Precision and specificity are metrics commonly used to determine a model’s performance in a classification problem.
How to Answer
Explain that precision measures the proportion of true positive predictions among all positive predictions made by the model. In contrast, specificity measures the proportion of true negative predictions among all negative predictions made by the model.
Example
“Precision and specificity are both important evaluation metrics used in classification tasks, but they measure different aspects of model performance. Precision measures the proportion of true positive predictions among all positive predictions made by the model.
On the other hand, specificity measures the proportion of true negative predictions among all negative predictions made by the model. It tells us how many of the predicted negative instances are actually negative.”
18. Let’s say you have to draw two cards from a shuffled deck, one at a time. What’s the probability that the second card is not an ace?
Probability is an essential building block in any data science project, as it provides a reliable estimate and interpretation of an analysis. Therefore, you can expect this kind of question to be asked in a data scientist interview at IBM.
How to Answer
Demonstrate your understanding of conditional probability by mentioning that the probability of drawing a non-ace card on the second draw depends on whether an ace was drawn on the first draw.
Example
“When drawing two cards from a shuffled deck, the probability that the second card is not an ace depends on whether the first card drawn is an ace or not. If the first card drawn is an ace, there are now 51 cards left in the deck, of which 48 are non-aces. Therefore, the probability of drawing a non-ace as the second card, given that the first card drawn was an ace, is 48⁄51. On the other hand, if the first card drawn is not an ace—there are 52 cards in the deck, of which 48 are non-aces. Hence, the probability of drawing a non-ace as the second card, given that the first card drawn was not an ace, is 48⁄52.
Therefore, the overall probability that the second card is not an ace is the average of these two conditional probabilities, weighted by the probability of each event occurring as the first draw, which is 4⁄52 for drawing an ace and 48⁄52 for drawing a non-ace. Therefore, the overall probability is (4⁄52) * (48⁄51) + (48⁄52) * (48⁄52) ≈ 0.9038.”
19. How do you handle imbalanced data?
Imbalanced datasets are extremely common in any real-world data science project, and there’s no exception to this at IBM. Therefore, data scientists at IBM need to understand the theory behind how to deal with imbalanced data.
How to Answer
Discuss various techniques for handling imbalanced data, such as resampling methods (e.g., oversampling, undersampling), algorithmic approaches (e.g., cost-sensitive learning, ensemble methods), and evaluation metrics tailored for imbalanced datasets (e.g., precision, recall, F1-score).
Example
“Handling imbalanced data is a common challenge in machine learning, and several techniques can be used to address this issue. One approach uses resampling methods such as oversampling the minority class or undersampling the majority class to balance the class distribution in the training dataset. Another approach is to use algorithmic techniques such as cost-sensitive learning, where misclassification costs are adjusted to reflect the imbalance in class frequencies.
Additionally, ensemble methods such as bagging and boosting can be effective in handling imbalanced data by combining multiple classifiers trained on balanced subsets of the data.”
20. Given an employees table, how can you write an SQL query to get the total salary of all employees?
As you’ll be working with big data at IBM, SQL is a must-have skill for data scientists. If you’re good at SQL, you can efficiently retrieve the necessary data for your data analysis project.
How to Answer
Write an SQL query that selects the total salary of all employees from the employees table. Make sure the query is syntactically correct and efficiently retrieves the required information.
Example
“This query selects the sum of the salary column from the employees table and aliases the result as total_salary. It calculates the total salary across all employees in the table.”
SELECT SUM(salary) AS total_salary
FROM employees;
