The question is, is this going to look bad from any potential future
employers point of view?
Certainly you suspect it will won't look great, or you wouldn't have posted this question. And you are right - short-term jobs always raise a red flag.
As a hiring manager, I want to hire people for the long haul so that I can invest in them professionally.
Whenever I review a resume, I look for job duration in prior jobs. If I see jobs of less than two or three years, I wonder why.
- Perhaps the candidate wasn't a good fit for the job. I wonder why wasn't the candidate able to discern that bad fit before signing on?
- Perhaps the candidate was let go. I wonder, in what way did the candidate fail?
- Perhaps the candidate got bored and left. I wonder, what bores this candidate?
- Perhaps the candidate is hopping for a slight pay increase. I wonder, how much more pay is needed to cause this candidate to leave?
- Overall, I wonder - will this candidate be able to stick around here, or will he/she be gone soon?
This isn't a black-or-white issue. One short job probably isn't a career-killer, particularly at the beginning of your career where you are basically considered "less mature", and "less settled" anyway. But more than one might indicate a pattern. And several short jobs in a row tend to show an ongoing issue.
If you do get past the resume review, and into an interview situation, be prepared to explain why you left any short-term jobs, and be prepared to explain to the interviewer why it won't happen at their company.
I would never recommend that you actually plan on a series of short-term jobs, unless you have no other options. Far better is to suck it up in your current job until you find a job that you are comfortable will be long-term. That demonstrates some maturity and professionalism.
