3.1.1 Given a string, write a function to find its first recurring character.
Approach this by using a set or hash map to track seen characters as you iterate through the string. Discuss time and space complexity, and consider edge cases like empty strings or no recurring characters.

3.1.2 The task is to implement a shortest path algorithm (like Dijkstra's or Bellman-Ford) to find the shortest path from a start node to an end node in a given graph. The graph is represented as a 2D array where each cell represents a node and the value in the cell represents the cost to traverse to that node.
Explain your choice of algorithm based on graph properties, and walk through how you would manage visited nodes and update path costs efficiently.

3.1.3 Create your own algorithm for the popular children's game, "Tower of Hanoi".
Describe the recursive solution, base cases, and how the algorithm ensures all disks are moved according to the game’s rules.

3.1.4 Given an array of non-negative integers representing a 2D terrain's height levels, create an algorithm to calculate the total trapped rainwater. The rainwater can only be trapped between two higher terrain levels and cannot flow out through the edges. The algorithm should have a time complexity of O(n) and space complexity of O(n). Provide an explanation and a Python implementation. Include an example input and output.
Discuss the use of two-pointer or stack-based approaches to efficiently compute trapped water, and highlight the importance of optimizing both time and space complexity.

3.1.5 Find the closest sum to a target value of three integers within a list.
Explain your approach to sorting the array and using a two-pointer technique to find the optimal triplet sum, while keeping performance in mind.

3.2. Data Structures & Optimization

You’ll need to show a deep understanding of data structures and their real-world applications, as well as how to optimize solutions for speed and memory usage.

3.2.1 Median O(1)
Discuss data structures that allow for O(1) median retrieval, such as dual heaps or balanced trees, and explain how you’d maintain them during insertions and deletions.

3.2.2 Implement Dijkstra's shortest path algorithm for a given graph with a known source node.
Outline the steps for maintaining a priority queue (min-heap), updating shortest paths, and handling edge cases like disconnected graphs.

3.2.3 Write a function to impute the median price of the selected California cheeses in place of the missing values.
Describe how to efficiently compute the median and update missing values in-place, considering both performance and data integrity.

3.2.4 Write a query to compute the average time it takes for each user to respond to the previous system message
Explain how to use window functions or self-joins to align messages, calculate response times, and aggregate results by user.

3.3. Machine Learning & Data Analysis

MeUndies values engineers who can bridge software development and data-driven insights. Be prepared to discuss machine learning algorithms, data cleaning, and experimentation.

3.3.1 Implement the k-means clustering algorithm in python from scratch

3.3.3 How would you build an algorithm to measure how difficult a piece of text is to read for a non-fluent speaker of a language.
Describe possible features (e.g., sentence length, vocabulary complexity), model selection, and how you’d validate your approach.

3.3.4 The role of A/B testing in measuring the success rate of an analytics experiment
Explain how to design, implement, and interpret A/B tests, including hypothesis formulation and statistical significance.

3.3.5 Challenges of specific student test score layouts, recommended formatting changes for enhanced analysis, and common issues found in "messy" datasets.
Discuss strategies for data cleaning, restructuring, and how to automate detection and correction of common data quality issues.

Highlight a specific instance, the reasoning behind your decision, and how you communicated the tradeoff to stakeholders.
Example: With a tight product launch deadline, I prioritized delivering a working prototype, while documenting areas for future refinement and validation.

3.5.8 Share a story where you used data prototypes or wireframes to align stakeholders with very different visions of the final deliverable.
Describe how early visualization or prototyping helped clarify requirements and drive consensus.
Example: I built interactive wireframes to gather feedback from marketing and product teams, which helped us converge on a unified dashboard design.

3.5.9 Give an example of automating recurrent data-quality checks so the same dirty-data crisis doesn’t happen again.
Explain the problem, your automation solution, and the resulting improvement in data reliability or team efficiency.
Example: After repeated issues with duplicate records, I implemented scheduled de-duplication scripts, which reduced manual data cleaning by 80%.
