I used to say “sorry” each time I had blocks, which drained the last pieces of confidence and didn’t do any good whatsoever. Had to learn to stop doing that also. When I met my first recruiter ever a week after our phone call (which was physically and mentally exhausting) he said something like “What were some of your tasks on your last job position? I didn’t record our conversation and couldn’t exactly remember.” I said something like “Ha, even better!” thinking how he wouldn’t had to go over that painful call again but he was confused by that comment, which made me even more confused as he probably wasn’t looking at it the same way as I was. Anyway, regret nothing, next time you’ll know exactly what to do and what not. You’re learning along the way
