Once you get your first job, the certs of all kinds just become resume fluff, but since you are pursuing your first job, they might be useful.
As an interviewer, I think that certs are only useful if you take the test with a different company than you studied with. So I don’t think I’d care if you have a coursera cert, because I’d assume it just meant you finished the course that you paid for.
What certs are you thinking about doing, and more importantly, what are you looking to get out of them? I know “a job”, but what kind of job are you looking for?
