Don’t Be Afraid To Ask Questions: Most of the job seekers fail to make a impression to employers thinking that an interview is a one way street and miss on opportunity to ask question while the interview takes place. 
Instead, individuals should come prepared with a list of questions to ask before and most importantly make sure there is no question asked related to salary unles it’s your 3^rd or 4^th job interview. If additional questions arise during the process make sure you just chart it down and ask when required as this process is an effective way to organize your thoughts. Moreover, it also creates a good impression in the minds of the employers and also clarifies that you’re up for the challenge with opportunity provided.   
Badmouthing Past Employers:  You may have had most unhappy times at your past work place. But that doesn’t mean that you have to crib about it and make a fuss while giving an interview.
As it’s a small world individuals should not give the opportunity to the interviewer to think that you might speak the same way about his or her company when you quit the job.  
Instead individuals should spin a positive experience that they gained from their past work and make sure that they make their intensions clear that they will work for the company as well as their individual growth.
