Interview Preparation Tips

Interview preparation tips for other job seekers - This is my personal experience with Netcracker Gurgaon.

In the face to face round with their so called Gurgaon head Ankit Jain who himself told hadn't had a hands on in 8 years, he tried a lot to prove his superiority rather then showing interest in what I know. He specifically told me that na offer from South India should be a problem for me as I belong to northern part of India.

After clearing all rounds with the organization, the HRs continued the discussion of offer letter for 20 days.

To them a guy from north because of the location can be low-balled and will settle for lower offer, ignoring its competency level.

An organisation that has no regard for their probable employee, will definately disregard the one they have.

My two cents, don't join the organization.
