bp Senior Software Developer interview questions

Online tests and solving real time problems using virtual environment. Two technical rounds, both were online. Difficulty level for the first round is easy but the second one was tough as less time to write a script.

An awful experience, applied through a recruiter, where it take them ages to respond. I applied through the agency on med of May and heard their final response on 9th of July. The process started with the first stage technical test about B tree and Linked lists. The second stage, first they sent me a wrong interview, and the interviewer there 10 minutes late for the wrong interview 😂. It toke them more than 2 weeks after the wrong interview, to reschedule the correct second stage interview. Where the first hour was technical question, the guy was nice and if you know your field and prepared nothing to worry about. However, during the technical questions there were some behavioural questions. After the first hour technical question, I another 2 joined the call and start asking behavioural question, although the guys were friendly, the interview were so long, as it last almost 1 hour 45 minutes. The last stage interview was just over an hour, and it was purely technical, about cache and performance. It is worth to mention after they sent the wrong interview for the second stage, they moved my application to a sister company. The process is annoying, because you have to wait weeks between the interview stages. Also, I had to chase the recruiter a lot, by emails and calls to get a feedback. After many weeks of chasing the recruiter to get a response. I had my response "it is NO for you", that's it. It is annoying to go through such process and get such feedback without any explanation from one of the biggest company in the UK.
