Even before stackoverflow was available, my ability to solve a problem on the spot was probably not that great so my success in passing technical interviews seems like a lot of luck in hindsight - in my actual work I had to solve similar issues in successful technical interviews, and this is over four different industries/positions. This is versus unsuccessful ones where I haven't looked at the thing in question in years or ever so I am pretty much going in cold on the question. I've seen some people talking about going through every question on leetcode or hackerrank and being able to recall a solution instantly to prep for a Google style interview so you have to ask yourself if you think it's worth that kind of effort. Don't take your lack of success now as a very good measure of your ability, it sounds like your company might not hire you if you applied to it even though you are really good at your job.
