The Coding Round Did Not Match Earlier Reports

Process: OA → HR BQ → ML Case → ML Knowledge → Coding, for four interview rounds in total. I should be done here. OA: The same questions as the 2023 version on the forum. If you read through the interview reports here from beginning to end, you should basically be fine. HM BQ: The questions went into more detail than I expected. There were a lot of self-evaluation questions, such as what I though…

The Coding Interviewer Never Appeared

This company still has an online OA, which I found a little surprising. It included some multiple-choice questions, and the last problem was a divide-and-conquer problem, LeetCode 395.

One Interviewer No-Show, One Walked Out Mid-Interview

I mass-applied online, and HR reached out to set up an interview directly — there was no HR phone screen first. They never shared the job details or the salary range, and went straight to scheduling a 30-minute behavioral round with the hiring manager. The behavioral round with the manager went okay.

What are interview experiences?

An interview experience is a candidate's own account of a hiring loop — not a question bank entry. It tells you the shape of the process: how many rounds there were, what each round actually tested, how long the gaps between them ran, and what the recruiter said at the end. That context is the part a question list cannot give you.

How to read them

Weight recent write-ups more heavily — interview loops change, often within a year. Read several for the same company and role rather than one: a single account tells you what one interviewer asked, while five tell you what the bar is. Note the outcome badge too, since a rejection write-up usually explains the gap far more precisely than an offer one.
