Senior Software Engineer Interview Experience - London, England
Process
Two coding questions, two design questions, and a round with the hiring manager. All technical tasks were very focused on understanding and explaining the solution rather than strictly the most optimal solution. There was lots of time to go deeper and cover details, though. All of the interviewers were perfectly prepared and very happy to share insights about the company and answer any questions.
