Applied online, received a test on CodeSignal in a few days—average/hard, have done only about 60%, got ghosted after that (nothing in response, candidate cabined in workable is also empty)
I applied through a recruiter. The process took 2 weeks. I interviewed at Capital One (London, England)
Interview
The first round was an online assessment of CodeSignal. This assessment had some real problems to solve (no leetcode type). I enjoyed solving the problems. I got positive feedback and the next round was scheduled.
I confirmed with the interview about the format of this second round. Is it the same assessment with real coding problems or leetcode type? He did confirm that there would not be Leetcode-type questions or tricky questions.
I appeared in the second round and you know what the interviewer asked me Leetcode medium problem. Isn't it strange? There is nothing wrong with asking Leetcode types of problems. The only concern is that you prepare your mind for that. You know what you are asked in the interview is different from what you do in a real project. But I loved the questions asked in CodeSignal.
The recruiter shared the feedback and asked about my availability to discuss the feedback. I shared my availability but he never responded to that email.
