Software Engineer Internship Interview Experience

February 2, 2026

Negative ExperienceNo Offer

Process

Automatically received email for OA right after applying, had to take within two weeks after application.

OA was 2-3 leetcode mediums / hards.

Online interview on Zoom after passing OA.

Questions

Asked some abstract system design questions, like giving some API or method and asking a way to implement some system efficiently. But the interviewer was late by five minutes, sped through the explanation verbally without any written text, and answered in a very irritated voice when I asked back for clarifications. Wouldn't want to work with them.

Pros: The company puts a lot of effort into making it a workplace that everyone loves. You are treated like a valuable asset to the success of the company.

Quarterly bonus and a lot of office travel. A lot of recruiting opportunities for internships and experienced professionals. I would recommend it for anyone bored of hedge funds or banks.
