Received an email for a phone screen less than a week after applying.

After screening, they sent a link for a CodeSignal technical assessment, which wasn't too bad. It consisted of three parts, each iterating over the previous implementation. I really enjoyed it as it was more practical than the usual LeetCode-style problems.

A day or two later, there was a system design interview. I felt like I over-prepared, but essentially, I was explaining in detail a feature I implemented in my previous role.

The final step was a three-hour final round interview. The first part was a simple Weather App assignment with an obscure library to test how you problem-solve and look up documentation. I definitely did not perform as well as I could have here, as I was stuck on the obscure library. The second part dealt with an existing Python/SQL script, which we had to review, optimize, and spot any mistakes or security concerns. Finally, it ended with an interview with the hiring manager, which I can't recall at the moment.

Overall, it was a positive experience. The only reason I put neutral is because I don't believe they were upfront about hybrid; it sounded like they will transition to full on-site soon.

1. Initial phone screening.
2. CodeSignal assessment.
3. System Design interview.
4. Three-hour final round interview (Weather App, Python/SQL, Hiring Manager).

Be prepared to go through documentation on an obscure library live (e.g., PonyORM).

Be able to troubleshoot and modify/optimize code.

Explain a difficult project, system design-wise.
