Is it still hard to find a job because of COVID?

I’ve been employed for the past two years at the same place but I want a new job TERRIBLY. I’m unhappy and having no luck finding a job. I’ve been looking pretty consistently for the past few months and seem to have promising job interviews. The employers seem interested and tell me they’ll get back to me. Either they never do or obviously give me the bad news that I did not get the job. Even though, it seems promising in the interview process. I’m so frustrated, I’ve known of people able to get a job at this time. I can’t find a job, I can’t tell if I am having a hard time or if it’s because of covid. But things have gotten better and places are opening back up. I’m told I didn’t get the job because the role was offered to someone else. People are obviously hiring but just not hiring me. Why can’t I find work? Is it really due to covid?
