I applied online. I interviewed at HackerRank (Sat home) in July 2025
Interview
Was selected in the initial screening round. They scheduled a technical coding round. In the email they mentioned the interview will involve solving real world problem with AI assistance. So I focused less on Leetcode and more on low-level design questions. But the interview was pure Leetcode questions. Solved the first question, but was only able to give a brute force solution for the second one.
I applied online. The process took 1+ week. I interviewed at HackerRank (Bengaluru) in Sept 2020
Interview
Was sent a link for a developer hiring challenge via email. It had two easy string-based programming questions with a time limit of 75 mins. The first round was on codepair with 2 questions based on ds and algo was about 45mins long. The second round was a take-home assignment to implement an API time provided was 48hrs. The 3rd round was on database design.
For the take-home assignment faced a lot of issues with the environment - the python and django versions were outdated, the preview browser wasn't working, and the online ide crashed for hours at one point. But they considered my candidacy for the next round despite not being able to run of the 5 test cases successfully.
Interview questions [6]
Question 1
Round 0 - Check if every letter in a string is repeated once or less.
Round 1 - Given a set of numbers S (no repeats) and value t, find the number of unordered pairs you can form with the difference of t using values from S.
Round 2 - REST API for Github that allows you to add, delete, update, read events (git events) of a particular actor on a particular repo. Also had to do /GET on actors while arranging them on basis of number associated events, event streak etc.
