everyone leaves the previous job for a good salary and good careerbut don't say as in front of ur interviewer. don't tell dirty things and weakness of ur previous company. it gives a bad effect of ur character. always give a reason which is not abt ur company. always tell a problem that u didn't work in prevous company. and tell abt ur positive things wen asked abt utself. not tell ur negative points. always tell positive points whether u hv or not
