How to prove to an interviewer you will be commited to spend a long time in a job?

become a good lier.

What reason would you give?! It's very difficult to give a justifiable reason for leaving a job after 3 months, especially if it's a grad job or something serious, well it must be a serious job if OP is asking for advice otherwise he wouldn't bother putting it on his CV.

They will probably check your reason out when they phone for a reference...no point in lying, it'll just catch up with you...unless your going for very low skilled work, which in that case, referees are never checked.

I was employed in my first full time job for a year before the post was made redundant and found employment pretty much straightaway and have been in the new job for around 3 months. I don't like the new job and would like to leave but will this look like I'm not committed/a job hopper?
How would you explain in an interview without the interviewer thinking 'I'm not going to employ this person if they are going to leave after 3 months!'.

I want to be committed to a job and grow with a company but this role hasn't been what I expected - how to explain this in an interview/applications though?

I've conducted a fair number of interviews, a lot of them for trainee/apprentice positions where I definitely didn't want people moving on quickly.

There's not a lot you can say expressly. Most people with half a brain (or less) say the same old things anyway - how committed they are, how they want to do quality work and so on.

The "tells" are usually an aside, or not part of the main question "are you in this for the long haul?"

Someone likely to move on quickly can often give an indication based on something like very strong outside interests, a very chequered work history (including positions like the one interviewing for) and qualifications. If someone has a degree in Biochemistry, it's difficult to accept that they will take an apprentice position as a Sky TV installer, and won't move on if something more congruent to their degree comes along. Similarly, if you are interviewing a girl (and it's usually girls) for an admin position in your sector and they talk at length about charity and do-gooding, you can be pretty sure that as soon as some cool HIV/homelessness charity in Farringdon offers her (even on less money) her feet won't touch the ground on the way out.

I interviewed someone once for trade apprenticeship, and his CV was covered with football coaching qualifications (as hobbies) and he seemed to spend all his spare time doing it. In his interview he talked about how he loved coaching football in his spare time. We offered him the role, and he accepted but he didn't show up for his first day - I heard he took a job working at a football 5-a-side centre instead.

Another thing to be wary of is over-ambition. It's very easy to come across as "I want to learn everything I can in a short space of time, so that I can leave here and set up on my own or go to one of your rivals" For employers - this is worse than just leaving - this is leaving and becoming competition.

Applicants actually say this at an interview?! How stupid! Sorry, but surely that's rule number one, don't let the employer know you're just there to use them as a stepping stone for experience/get qualifications. I.e if applying to the big 4 for auditing and ACCA, don't say to them you're leaving once you're qualified in 3 years...

Ha, future doctor...you'd be lucky to be a bin man with that sort of response. Good luck becoming a doctor though, I'm sure you're personality will shine through during interviews.
