I think I've been pretty lucky with the jobs that I've had so far in my career where none of them have required extensive whiteboarding for their interview processes. I completely empathize with you though, as I feel like every time I've encountered whiteboarding in an interview, I must've seemed so incompetent to the interviewer. It's definitely possible to find jobs that don't require whiteboarding for their interview process - best of luck when you look again!
