Tons of them. How much time do you think the typical actor or dancer spends auditioning and preparing for the audition? How much time do you think people in many creative fields spend putting together portfolios? And if I'm going to interview with just about anyone, I'm going to spend at least 4 hours prepping for an interview.

I'm not a big fan of take homes in general but a time-consuming job search and interviews is absolutely normal beyond low-skill jobs in a time of labor shortages.
