Software Engineer (Internship) Interview Experience

October 1, 2022

Positive ExperienceNo Offer

Process

I had a 30-minute phone screening.

I was asked about compilers and language properties, and why I want to work at MongoDB.

It was a pleasant experience.

I received an email the same day to proceed to the next step, which was a Karat interview.

I solved one question within an hour, but time was up for the follow-up question.

I received a rejection email after two days.

Questions

Why MongoDB?

The difference between your two favorite programming languages?

Is Python JIT?

Karat: It was about string manipulation and arrays.

Amazon culture forcing its way through

Software Engineer • Current Employee

October 21, 2026

Pros: Not much that I can think of.

Cons: Amazon culture is being forced down the throat. Most of the hires are from AWS. The culture was supposedly good, but the work-life balance is getting worse and worse while more and more meetings are occurring. The Observability org is particularly bad for this, but the AWS culture is everywhere.

Good company, great compensation, but not without problems

Engineering • Current Employee

November 24, 2020

Pros: Great company outlook. Generous company stock and overall package. Work is interesting if you like databases.

Cons: Female engineers are rarely promoted. Scepticism in female engineers' capability across the board. If you are a young female engineer, being explained things you'd obviously know is such a common encounter. Work-life balance is hard to guarantee. Mid to lower-level management can lose track of the greater goal.
