Flagship Pioneering interview questions

The interview process was very well structured and described in detail; recruiters were very responsive. About four sessions on the technical questions about random topics on ML and the application (standard for an ML position), and a presentation. At the end, I didn't get the job, but I appreciate not getting ghosted, a genuine rejection letter (not an automated email from a no-reply account), and the detailed positive feedback, so it was easy to interpret areas of opportunity.
