casual chat with the CEO about company and my background. then had a technical interview with some probability questions and problem solving that was interesting.
then i had the "onsite", starting with the VP of engineering, a general problem solving interview. then another interview where you had to wrangle some data in a notebook, and finally a third one with a lot of ML and deep learning questions. overall, tough but fair.
then they ghosted me. i understand we're all busy, and getting ghosted after first and second round is still passable but after an onsite is bad. if i didn't cut it, that's fine, but just let me know. i wrote follow up thank you emails and asking them what's up. never heard back from them
