3 rounds of interviews (15 minute chat, 45 minute in depth, 1 hour presentation and further in depth with founder and VPs present).
Throughout the process they were rather slow and bad a communication. At the end they said "we'll get back to you by Friday" (it was Tuesday). Then they ghosted me and didn't respond to any of my professional follow up emails. 10/10 wouldn't recommend to anyone cause they might just waste your time and not have the decency to even tell you why or if you are getting the job. Highly unprofessional.
