My favorite is when you apply for a job and you get there and magically the job title/responsibilities have changed. It's like, y'all don't even know what you're looking for… get bent.
Definitely yes, majority will do full day interviews and reject you because you can't write on a white board.
I'm also guilty for spending lots of after work days studying for jobs I really wanted and getting rejected but at least I didn't burn any of my precious vacation days.
Apparently I was wrong.
And no, it was just a regular programming job, nothing special.
Northrop Grumman had a (wasteful) 8 hour "college day" that was an hour of technical interviews, 4 hours of propaganda, and 2 hours of arbitrary fluff like team building games among the applicants.
The ~5 or so on-sites I've had apart from NG were 2-4 hours.
I got my current job after a brief phone screen and a one hour in-person interview. It came with a big pay increase and the smartest people I've worked with so far.
I'm not sure why so many companies insist on the days-long torture interviews (I've been through several), but I know they're not necessary to find good people.
I got reasons like "the interviewer quit without submitting his feedback" or "interviewer said he had hard time understanding your voice on the phone" (I'm a native english speaker and interviewer was not), or "interviewer lost his notes", etc. Maybe my code just sucks and they were lying but I don't think so. It took so long to get through that stage to the onsite that I felt like I'd already worked there.
