Technical Coding Behavioral System Design
This was the best onsite interview experience I've had, with great interactions from recruiters, engineers, and the engineering manager. The recruiter clearly put a lot of effort into optimizing the process. The technical challenges were engaging because they mirrored real issues faced by Postmates engineers, making them both tough and educational. The interviewing engineer was very patient in explaining anything I didn't grasp. It seems the engineering culture has gotten much better, or at least this team is exceptional. The manager even reached out on LinkedIn.

Coding Behavioral
I applied online and they reached out to me for the internship role. I passed the online coding challenge and then had to do an online behavioral assessment. After that, I was supposed to schedule an interview, which I did, but then they ghosted me for two weeks. I followed up, but still nothing. After three weeks, they emailed saying they filled the positions for the current season and would consider me for a different year. I scheduled again, and again, they ghosted me for two weeks. Finally, they sent a rejection email without an interview, leaving me confused and stressed about the ghosting.

Coding Other
They send you an email to do a coding test on Codesignal. The problem is they want to video and audio record you the entire time. I'd be fine if they just wanted to screen record. Like cool, you wanna make sure I don't cheat or w/e. Cool. But now you're introducing bias into the mix. Now I gotta worry about smiling and all that jazz, instead of coding. Yes, because they will see it. Yes, they will judge you. It's human nature to subconsciously judge. It just throws into the mix all other sorts of biases. Obviously you'll have to meet in person or video conference at some point, but it should be after a coding challenge not before it. You're allowing subconscious bias to play a role now, instead of just the code. As a minority in tech, I'm always conscious of it. It's why I "whiten" my resume and leave off my last name. Considering how "#woke" they portray themselves (LGBT pride galore for example), you would think this would come to mind. But whatever, I declined the interview based on this alone. Plus they are getting bought out by Uber anyway, and their record is horrendous when it comes to this stuff.
