Do people have hard time blocking out their calendar for interviews? For initial recruiter call (15 mins) or tech phone screen (1 hr), I just block that hour on my calendar. For on-site (virtual now), I just take a PTO. Last time around, I used about 7 PTO days for interviews (yes, 7 companies). I got an offer that I was happy with.
