1. In the HR screening, I was asked about my experience and why do I want to leave my current role? Also, I was told about the salary, the company, and the job description. 2. In the managerial round, the manager asked me about my most proud project and how I managed to get it done. 3. In the coding round, I was asked a question from data structure and algorithm which was following: You are given a list of integers, e.g.: [1, 2, 3, 4, 5, 6] called "l". You are given an integer w. Write a function that calculates the moving average of window size = w over l. Moving average = average of the previous w elements, including the current element Input: w = 3 l = [1, 2, 3, 4, 5, 6] Output:, [1, 1.5, 2, 3, 4, 5] Then I was asked to optimize the same.

You will be improving the function you developed prior to interviewing and will be thrown a lot of curveballs at the whim of the interviewer — because you won’t actually run your function or work with data be expected to be asked vague and poorly worded questions. This person will likely be extremely junior and have little tenure at the company or as a data scientist but definitely smarter than you — they may have taken a coursera course on modeling — so don’t expect to be able to prepare or get an offer as its extremely arbitrary and has nothing to do with your experience or ability to add value other than writing perfect code on the fly while being interrupted with vague questions with apparently very specific answers.
