Capital One Software Engineer interview questions

Recruiter contacted me and asked me to apply for the position. Passed a codesignal test and was invited for the power day. Round 1 Technical : Asked to solve a leetcode question. He told me to write the code in any language I want and when I wrote the code, he mentioned he did not understand C++ language . He goes on asking me questions about the code and do not understand what I am trying to convey. Round 2 Techincal: System design of a smart meter in an apartment. Very unprofessional, came in 15 mins late, connected through a mobile and wasted time and ultimately after 20 mins he connected through a laptop. Brags about how all their projects have moved to cloud. Asks me if I have experience working with AWS , and I answered I am aware of it, but have not used it much. Asks me about front end when I have applied for a backend position. Makes cutting sarcastic remarks such as all their developers are AWS certified and have knowledge on front end . I ask him a simple question why they selected AWS and not any other cloud services and he could not come with an acceptable answer. Round 3 Case Interview : A business scenario and discussing the pros and cons of using a product and some interpretation of the code. Won’t give me one minute to think, kept saying “speak through your thought process” a hundred times . This interviewer also talks about cloud. Round 4 Behavioural : Reads from a paper and asks 3 questions. Overall, they are very obsessed with cloud and AWS. I would suggest that they do a thorough resume screen before they invite people for the power day and waste everyone’s time. Also, they want you to understand the question, think about it, write the code, also keep talking in the background . I am not sure how you can do all that. The worst part is the recruiter calling you to tell you that you have been rejected when an email would have been sufficient
