I am a linux professional looking for my next devops/sysadmin etc roles. I am tired of applying and getting my resume rejected. For a few days though since I tuned my resume, I am starting to get calls for interview. But I get rejected in interview as my knowledge probably isn't as good as those with 10 years of experience.

Now, a RHCSA certification would make me do linux administration on my sleep. But having a small lab over my spare laptop(I only have office laptop at this moment) would help me crack the job given I get till interview. However, a red hat cert will get me towards the interview.

My monthly saving is very low (Near about 80$) and I'd need 3-5 months of savings to afford a certification.
