Twice they cancelled and attempted to reschedule interviews for the third round panel, each time only hours before the scheduled start.
During compensation discussions, equity was emphasized, which I appreciated, but concerns I had about dilution were never clearly addressed.
Overall, the process raised concerns about organization and professionalism.
