I was initially called by my Flipkart HR directly to talk in for the interview. It was a whole-day process, starting from morning to evening on a Saturday.

First was the coding round where we were given a problem and had to do machine coding. Tips for this round: do not worry about making the code work; just write as many test cases as you can. Also, make the code modular and easily readable. Talk to the interviewers about your design assumptions. If you ask them questions and get clarification, they really appreciate it more than you starting to code immediately.

Prepare for the data structure, algorithm, and design rounds thoroughly; it will not be a cakewalk.

The Data Structures and Algorithms round was really difficult to crack, but it shows the quality of people who work at Flipkart.
