Perfios Campus Placement Experience
Perfios had recently come to our college to recruit interns and full time employees for the role of Software Developers. We had to go to their office for the process.
First we had an Aptitude round, which was of intermediate level.
After that they gave a presentation about the company.
Everyone who had taken the Aptitude test had to take a coding test.
The coding test was written and had 4 questions.
1. rotate the characters of a String by k times
if the input is abzi and k is 2
The string becomes cdbk
