Interview Preparation Tips

Interview preparation tips for other job seekers - Interviewer was so excited to hire me. But when I asked HR Nidhi what happened on releasing offer letter . She said we are interviewing other candidates I need to wait .
I mean why should I wait ,it supposed to be a yes or No. After a month she said we finalize other candidates when i asked the reason she said multiple reason . It's funny that if my candidature have so much of reason to be rejected then why would you wait a for a month.
The fact is they don't have a budget to pay . It comes to picture when my friend talk to the manger . F.y.i I was referred by my friend .
These kind of company makes the entire interview process a mockery . They should have check there budget before hiring .
If you have budget to buy a maruti when even you go to BMW showroom.

I suggest if anyone is interviewed by this company . Please check they have a budget to pay or not and how soon you can expect a offer letter !
