OK, You have a degree
What is your experience like?
What is your field in tech?
What make you senior?
Another important question, where are you located? This can make a huge difference, if you are looking in a small town for senior tech jobs then you aren’t going to get much.
Right now, tech jobs aren’t doing well since companies over hired, then decided to shed those positions. But Senior positions are usually always in demand.
If it’s not your experience, then I would look at your interview skills.
Your resume only gets you a conversation, you have to sell yourself to them.
Are you confident when you interview? Not too confident to be cocky though, but enough that you know what you are talking about if someone were to ask a question.
Ask questions during the interview. Ask them what they like about working there. Act interested and engaged and you will stand out among the rest.
