Factual Software Engineer (Data) interview questions

30-minute recruiter phone screen followed by a coding challenge. Once you've submitted that, there's a 30-minute technical interview - mostly questions on data structures and CS fundamentals. Finally, there's an on-site interview with four members of the team and the founder himself. The focus of the interviews ranged from CS to data engineering, so be sure to prepare accordingly. The recruiter was friendly and helpful throughout, and the interviews were fair. Make sure you review regular expressions! A lot of questions involved them.
