BlackRock Software Engineer interview questions

I briefly met with one of the managers and had a behavior interview. We talked about tech, but didn't not do any algorithm questions. Once I got past that I got called in for an interview that lasted about 2:30 hours. I met with other senior managers and chatted with them one on one. Didn't really do any algorithm questions during those discussions. We did discuss tech stacks, and why we would use one technology over another one though. After that I received a take home assignment, which required me to build a small web application using React and Redux. I was applying for a frontend role which made sense. The application was a stock screener that retrieved data from an API that they had suggested and displayed some Security Information. After that I received the offer.

Similar experience to others posted here. Such a waste of time. April to June with seven rounds of interviews. Was told offers would be given after the onsite interviews. But no, positive feedback so another 3 rounds. And then still positive, but another person wants to talk to you so another round. There is absolutely no respect for your time, it appeared that they did not know what they were looking for. This last interview is totally disheartening, after all the time spent in the process, it appeared this interviewer did not even bother to look at my resume & asks me if my role in my past job was in coding or simply documentation. The tone of the interview was very rude and a blatant waste of time. This is definitely not a tech organization, no matter how much they boast they are.
