The interview comprises three parts:

• "Your Story"
• ~60 minute Technical
• On-Site (~3-5 more interviews, including more technicals)

I was rejected after the first technical.

The first portion is nothing to worry about. It's an internal recruiter or someone who works tangentially to the relevant team. They're looking for relevant experience, personal red flags, and generally getting you excited for the role.

Second interview was a remote call where I was asked to use my own IDE to create a solution to a technical problem.

What probably took me out of consideration was that I focused too much on the wrong part of the question, wasting 10-20 minutes. Otherwise, it should have been fairly simple.

Rejected after this.
