Career advice: Specimen Processor or Master's in Biotechnology?

Hello! I am seeking advice for my career path. I have an unrelated bachelor's and a vocational training program certificate in biotechnology and about 9months of experience in an R&D biotech environment, mostly doing immunoassays.

I've been having trouble getting interviews unfortunately as I moved to a more rural area and the job market is tough. I was admitted to a Master's program in biotechnology, but I also got an interview for a specimen processor role at a local anatomic pathology lab.

I'm interested in the specimen processor role mostly as a stepping stone to a MLT/MLS role actually performing tests on samples.

I am interested in the Master's program because I have enjoyed doing research and working in the lab in the past, but I'm eager to get back to working and worried about the job market as a whole.

I'm intrigued by the specimen processor role but worried that it will be mostly clerical with little room for advancement. Looking forward to hearing your thoughts!
