Normally when the company ask u to go for a 2nd interview, it means that you have gotten the job. 2nd interview normally is to tell you the salary, benefits etc.
Have anyone gone for a 2nd interview before and yet never get selected for the job? Meaning the company actually ask a few people to go for a 2nd interview and from there select one person?
1st or 2nd interview, is still, an interview.
There is no foregone conclusion u will be hired even if u make it to the 2nd one.
The ball is in their hands.
But i wish u good luck.
