FIS Senior Software Engineer (.NET) interview questions

Applied from a current ad on LinkedIn. Was contacted to do the usual first line screening calls, this was fine and was told my details would be sent to the hiring manager for review. Was then later told actually the job was already filled as they’d been at offer stage with another candidate before they even spoke to me. A waste of everyone’s time. That behaviour is very unprofessional. The ad is still on LinkedIn 🤷🏻‍♂️

Interview process is very good, 1 round is technical test, which is difficult. Then 1 program round, from array find the duplicate no count. Next round was technical face to face, they doesn't carry resume. They told me, they lost my resume. Intervier doesn't ask me any thing regarding. .Net, MVC, web api, c#, SQL. If you hiring for. Net developer, then you should ask questions on. Net & please carry resume in interview.
