Hiring manager screen, 1:1 interviews with head of sales and product, take-home assignment presentation, final round with COO.
My candidate experience was average overall but the final round with the COO was the worst interview experience I have ever had.
He joined the call 10 minutes late, didn't apologize, insisted he couldn't go past the scheduled timeframe, was very condescending and contrarian, clearly wasn't paying attention, and kept asking me repetitive questions from previous interviews.
After the interview and rejection, I felt like I'd dodged a bullet not working there. Not recommended.
