I’ve been jobless since May, and recently, I received calls from companies I’ve always dreamed of working for. It felt like my luck was finally turning around. However, I had interviews with them and completely messed up the first round in both cases. Over the past 15-20 days, I’ve had opportunities with some great companies for sales roles, but I just can’t seem to clear the first round. I feel really dumb about it. The questions aren’t even that tough; they’re mostly basic. Sometimes I just go blank, and I end up answering whatever comes to mind. Other times, I can’t structure my answers well, and even when I think I do fine, I still don’t get called for the next round. It’s frustrating. What should I do?
