1hr recruiter call (2-week delay for feedback). Completed a 1hr coding interview and was promised a response within 2 days. After waiting a week, I followed up and received an immediate automated rejection from a no-reply address. Disappointing lack of professional communication and courtesy.

Interview
Quite heavy interview process with 6 interviews and few calls with recruiter. Overall very pleasant experience. Interviews (especially technical ones) were highly relevant for the actual job.
The interviews:
- Hiring Manager Interview
- Technical Interview
- AI Workflow Assessment
- Scope of Influence + Customer Obsession
- Deliver Results + Ownership
- System Design + Operational Excellence

Interview
1. HR interview: Friendly interviewer. Learned about my background. Positive vibe but her English wasn't so good.
2. Technical Interview: A tech person started the technical interview right away. First theoretical questions, then coding exercises. He was checking other things while I was coding, although he helped when I asked questions. He didn't explain what he or his team was doing. He basically jumped out of the call as soon as the technical questions are over.
3. I don't know the rest of the process because the interviewer didn't care enough to explain it.
