IQVIA Senior Software Engineer interview questions

I was interviewed at IQVIA on May 2021. The over all process took 1 month . 1 online test followed by a technical discussion (1hr) and a managerial discussion (1 hr) and hr . After negotiating the salary and submitting all the documents and waiting for the offer Letter for close to 2 week and constantly fallowing up with HR they communicate that they cant hire you as they have already considered other people for the position. My feedback for the entire IQVIA team would be not to waste people time and trash there hopes after conducting all the rounds of interview and then not hiring.

First round was aptitude test which including Aptitude questions and programming questions including questions on basic oops and technical questions the questions was easy and clear enough to test my knowledge
