That is certainly a problem. I intentionally applied to companies I had some knowledge or interest in, but I definitely had to bullshit more when I knew less about the company. I tried to take the approach of putting my cards on the table; ex: I have a strong interest in security, automation, and devsecops, hopefully there is some intersection! Sometimes that worked, but I still ran into cases where I felt like I checked 9 out of 12 boxes, and by missing those 3 boxes they weren't interested, or they had someone who checked more then 9.

Either way, I have major respect for anyone looking for a new job right now. I wish you the best of luck, and I empathize with how exhausting it can be.
