I received a call from recruiting consultancy regarding a vacancy for C++ profile in Amadeus. The profile was quite interesting. After a week I received a call from Amadeus regarding schedule of the interview. 1st and 2nd rounds were scheduled on a Saturday at 12 PM.

After a week, I got a call saying I have cleared the first 2 rounds and selected for Director round.

Round 3:
This was the director round interview. I reached a bit late due to heavy traffic that day. But the director was very patient and spoke nicely.
The questions were mainly related to current project and expectations(theirs + ours). It took about 30 minutes.

After 3rd round I was asked to wait for their communication. I waited for around 3 days and received a call saying I have cleared all the 3 rounds and next will be the HR round.

Round 4

This was the HR round and had typical HR questions + some attitude related questions. It was a telephonic interview scheduled on an afternoon. The HR interviewer was typing my answers during the interview and hence it took around 1 hour.

1. Introduction
2. Resume related. Why I changed from my first company to my current company ? etc.
3. Academic scores.
4. Challenges faced during current project.
5. Roles handled in current project.
6. Salary expectations.
7. Future aspirations.
8. Personal information like DOB, etc.

Completed the interview and waited for about 1 week to hear from them. Later I inquired with the hiring team in charge. They informed me that its in process. I waited for another 1 week. Still did not hear from them and I was bit suspicious. Another week gone. After about 20 days of HR interview I was happy to receive the offer letter.

Overall interview experience was good.

All the best.
