MangoApps Interview Experience for SDE

This was my first interview experience with any company. They held three rounds.

Round:1

The first round was an online assessment that had time-bound sections. There were questions on CS fundamentals, Algorithm knowledge-based subjective questions, 2 to 3 General DSA-based coding questions, and two language-specific which were Javascript coding questions.

Round:2

After getting shortlisted, I went through 2nd round which was the HR round, It went for 40 minutes for me. I was asked to introduce myself, and about my future prospects, and I was asked to explain one of my projects which was mentioned in my resume. There were some tricky questions in between that you can expect based on how you answer your future goals.

Round:3

The third round was a technical interview round wherein selected candidates were given a coding problem and were asked to write its solution on a sheet of paper and the time given was 30 minutes, they were basically checking how optimally we can produce solution.

The question was to find the kth largest/smallest non-distinct number in an array of numbers ranging from negative to non-negatives.

The most optimal approach would be to use the quick sort algorithm.

After this, selected candidates had one on one technical interviews with one of their engineers, where we were asked to explain our approach to a given problem and how we can optimize it. Later on, some basic questions from OS such as multi-threading, from DBMS such as types of joins were asked to me and he asked me one specific question from one of the projects mentioned in my resume and later on some lightweight HR-based questions. 

That’s all it was.
