It seems like you are doing your best to improve yourself here, which is great. I wonder, however, if your skills are the problem? We are in an unprecedented economic situation, and I can't comment on the stability of the company you were laid off from. There are a few comments in this thread agreeing with your self-assessment that a person with your experience should have leadership capability. You probably should. That said, you don't know that is why you were let go. It may just be why you hadn't been promoted. A few of the places I have worked have been happy to let people hang out as senior engineers indefinitely. If I were you, I would reach out to your former managers and coworkers to see if they have any feedback they can give you. You would be especially well served by reaching out to a manager at a company that _didn't_ let you go. Do you have a boss you are still in contact with from a job you left voluntarily?
