I did 3 interviews so far this month and even though I didn't get any rejections, I still don't have any offers. Things around here do move slow(Australia) but I am not holding my breath.
2 of those interviews asked me questions about algorithms even though the job had nothing to do with that and I explained that I am not good at those puzzles and that I preferred to discuss my experience.
I don't know your situation but you have to keep trying. Even 20-30 interviews, whatever it takes. Not getting an offer from an interview says nothing about you or your abilities. Every single user on this site can tell you horror stories when they were looking for a job so you're not alone.
