Before the interview, there was an online coding test which consisted of 4 coding questions.

After that, candidates were selected for the interview round.

The interviewer focused mainly on the project. Since my project was related to an E-Commerce app, he asked me to design a user login system and how I would match the password from the database, including both encryption and decryption methods. I told him about the salt method.

Then, he asked me about the database design I used for my project.

He also asked questions related to Data Structures.

Given a number N, find the number of ways to represent this number as a sum of 2 or more consecutive natural numbers.

I don’t remember this question exactly, but in this question, we have to find the minimum length of the substring present in the circular string from which another given string can be made. This was solved using binary search and window sliding.
