IQVIA Clinical Data Manager interview questions

it was an easy Campus interview which had 2 steps Aptitude followed by PI Aptitude consist of basic maths and SQL questions. and the PI was very easy They asked me what is the difference between java and C and how you perform the DS in java. what is the range of integer and char.

There were 3 rounds. 1. CV screening 2. Written exam 3. Technical interview. Even though it was a walk-in interview, they managed well. And they replied about their decision in 2 days through mail. Though I was not selected, they approached me for their decision. In other cases recruiter just dont reply when you are not selected and u jst have to wait n wait.
