BlackRock Software Development Engineer interview questions

All-day interview with 2 stages. First was a 3-piece gauntlet with code review, system design and leetcode mediums. Second stage was interviews with matching teams for passers. Personally I did not like the recruiters' tone, which was a bit condescending and validated my fears reading others describing the company with engineers being treated as second-class citizens. At one point I was dropped in a meeting room waiting near an hour for a call. I was ready to get up and leave just before a recruiter came in unapologetically to see if I wanted to talk to another person. I said yes and after another 10 minutes of sitting it was over without ceremony. Got verbal offer by recruiter 'being blunt' and saying I should request less due to my 'lack of experience' before giving a range with me agreeing on the top end of it. Radio silence afterwards as company went into a covid freeze

It was a 30 minutes interview. The panel consisted of two people. I was first asked to introduce myself. They then asked me about my projects and the extracurricular. They also gave me a puzzle. I was asked to write an SQL query.
