Always log exceptions for debugging purposes, e.g...

Interview Preparation Tips
Salary part - I already communicated about I hold of offer 8 LPA and want hike on that. So Rohit said it can be possible upto 8.5 LPA. I said ok.
But after all discussion suddenly they said Cloudera is not ready to provide upto 8.5 LPA. They last can provide 8 LPA.
I agreed on it. Cloudera HR Monali called me. And said I will sent offer letter by EOD. But she not processed with it. I took follow up through Rohit on this. And Rohit said I will checkout with her. I said ok. Then for the same I take follow up on email. After that I got an call from Rohit to say ki aapka candituare proceed nhi ho skta.
I asked for reason and they gave reason like Aapka expectations high hai. When I already confirmed my expectations and your budget after that we come on this decision for 8 LPA. Then how is possible Cloudera don't have this much budget. And if you don't have budget why even you proceed with me.
They offer me again 7.5 LPA. It shows very unprofessional behaviour by both companies MNR solutions and Cloudera.
Suggestions - Mgt please look into it. And if MNR is right. Don't tie up with such companies like Cloudera. Don't waiste Candidate time.
