The interview process started with a very professional approach but ended being unprofessional. Overall, the experience was good, but it could be better. I applied for a Mainframe Sr software engineer role in Feb 2016 for Chicago location. Initially, I got a call from the recruiter (the recruiter was just great!). She asked for a copy of my resume and a couple of basic job related questions. Then I got an email with an online assessment link. The exam was 12 multiple choice questions followed by 3 coding questions. After this, I received email from recruiter that I passed the exam and they want a telephonic interview. The telephonic interview was purely technical with questions based on past projects and some mainframe/cobol. After this, they scheduled a face to face round. They provided the airline tickets, hotel and a luxury cab. I must say that I was impressed till here. The interview day was not good. There were 4 rounds with different managers. They were all confused. 3 of them were not even mainframe engineers. They read questions from a printed sheet and recorded my answers in the same. each round was 45 mins long. Most of the questions were behavioral and only the last manager asked me technical ones. Two of them were not even aware of the position I applied for. I applied for a technical lead in development area position, but on the interview day, one of the managers told me that they are interviewing for production support. This was totally unprofessional. I said a big 'No' for support as I never worked in support and dont want either. They could have told this at the very beginning and I would not have wasted my time. My advice for the mainframe applicants - *********** Capital one is doing away with mainframe and most of the work they have is just production support***** (I got this info from current employees while eating my lunch in cafeteria)*********** Eventually, all mainframe will shut down in the company.
