After lay-offs in my current company I was forced to job search on the market. During the process, I found a company specializing in a niche technology that I did my BSc with. I also use this technology for hobbyist work - however, I generally do not include the work in my general-purpose CV.
Not thinking much about it, I have sent the general-purpose CV to the company. I have yet to receive a response and I'm starting to worry that because my knowledge about this field is not highlighted in the resume, they have decided to skip me over.
Can I correct the mistake? If so, how should I proceed?
