    Interview Preparation Tips

    Interview preparation tips for other job seekers - A recruiter found me on Naukari Site the name of the person is Kartik (*****), and then, set up an initial L1 interview with the peers. The initial contact was a phone screen regarding the job location, title, salary, etc. in Banglore after that, he set up the meetings with peers for the interview.

    The interview was too good, but one thing which I feel bad Interviewer asked me salary while this is the part of the HR department, so why Interviewer asked me salary during an interview, this is totally not good for any candidate because if the candidate expectation is greater than the interviewer salary then definitely he will not hire that candidate that means.  



    After Interview:-

     Then, Kartik HR contact me again to tell that they are willing to offer less salary 14LPA than that was decided
    - I said yes, and they asked me joining date
    - I provided the next week date itself
    - But I never heard back from them afterward.
    - I tried to contact Kartik, but he is not willing to reply

    Very unprofessional behavior and bad experience. I don't know were they just wasting my time.
