Get your resume and skill set in order. I'm a software engineer with 30+ years behind me, and I always was working on cutting edge/current technologies - but still 30 years from college meant a lot of my algorithms - 'computer science' knowledge was in need of a refresher.
I also hired a company to do my resume because I hadn't done one in 15 years. I knew better than to rely on my out of date resume 'wisdom' .
If you start the process now - you will feel better about your prospects. I like freecodecamp as well as well as coderbyte. geeksforgeeks for data structures. Read up on your favorite software architecture styles. I like interactive websites - they give me instant gratification and it works better for me than reading large amounts of text. I wish the web was around when I was young.
