Zoho Corporation Data Scientist Interview Guide: Common Questions & Rounds
Introduction
The Zoho data scientist interview process runs 4 to 5 rounds, with the full process taking roughly 3 months from application to offer based on candidate reports. The prescreening includes a take-home classification task on a real dataset before any in-office rounds, which then cover coding with six problems, a technical discussion of prior ML experience, and a final HR round focused on compensation and location. Zoho conducts the in-office coding and technical rounds on the same day, back to back, rather than spacing them across multiple weeks.
Interview Topics
The Zoho Corporation Data Scientist Interview Process
Take-Home Assessment
Zoho sends candidates a classification task to complete before any in-office contact, and this assignment serves as the primary prescreening filter for data scientist and machine learning roles. One candidate reported: “Prescreening: Take home classification task for a dataset.” Performance on this task determines whether a candidate advances to the in-office day.

Programming Round
The in-office day opens with a programming round covering six coding problems, evaluated by Zoho employees who observe candidates in real time as they work through each problem. The round tests both implementation speed and the ability to articulate logic while coding, since interviewers ask candidates to explain their approach throughout. Candidates who cannot meet a minimum solve threshold do not advance to subsequent rounds held the same day.

Technical Interview
Following the coding round on the same in-office day, candidates move directly into a technical interview where interviewers probe previous ML experience and ask role-specific machine learning questions. One candidate described the structure as: “technical round to explain previous experience and ML related questions.” This round is designed to assess depth of applied knowledge, not just theoretical familiarity with algorithms.

HR and Compensation Discussion
The final round on the in-office day is an HR conversation covering salary expectations, location preferences, and background. Candidates report it is straightforward and focuses on logistics rather than behavioral assessment. One candidate summarized it as a discussion about the pay and location, confirming it is not a culture-fit screen in the traditional sense.

You are given an N-dimensional array (a nested list) and your task is to convert it into a 1D array. The N-dimensional array can have any number of nested lists and each nested list can contain any number of elements. The elements in the nested lists are integers. Write a function that takes an N-dimensional array as input and returns a 1D array. Example 1: Input: Output: Example 2: Input: Output: | ||
