You should reply honestly. Ultimately your boss could call your ex-boss and ask why you were terminated... Then your gonna be screwed because you lied or didn't say.
you can say the pay wasn't high enough
I left my last job because I'd like something a bit more challenging.
that you are a chubnub.
i left my last job because they fires me or i just didnt like it
I left my position in my last job for career advancement
The truth, or what you think is the truth, do not lie, you won't get the job.
Don't say "fired" when explaining why you left a job. Use something neutral, such as "better job opportunity," or "returned to school."
It depends but I'd suggest to always speak truth to avoid issues. Well I am currently working in studytubes.co.in from last 8 months and I left my last job for betterment.
I was looking for a job that challenged me intellectually.
When interviewing, ask what the last person who had the job did. Also ask how long they were in the job, and what they went on to do after they left the job.
