Frequent Service Breaks

These can signal many things.
1. Someone who is overestimating their ability and talking themselves into jobs they cannot do.
2. Someone who underestimating their ability and getting bored quickly with the jobs they get.
3. Someone without the ability for the job but who insists on trying none the less.
4. Someone psychologically unfit to work.
5. Someone with under developed social skills (I know one person who is brilliant at his job but has Aspergers, he needs special support but the company find his genius - literally - indispensable.) Some companies don't/won't support people like this.
6. Someone physically incapable of fulfilling that type of work.
7. An HR culture which discriminates against this person/group of people.
8. A "sellers market" to many jobs chasing too few applicants.
9. An HR environment where people are simply employed not developed.


I could go n and on and on but the one clear signal to me is bad HR practices whichever it is from the above list.

This is based on the candidate also because, if the candidate is genuinely keen into getting into a position he/she applied they wouldn't sell themselve but propose themselve for the position.

If the breaks in a person career is genuine it would show in the way he/she presents oneself during the interview.
