Vital Labs R D Software Engineer interview questions

Had applied through Freshers World, Where we had to give an online exam, 60 quest-60 min. Then qualified candidates were informed about the second round via mail. The second round was Coding Round. It was a pen paper round. All of us were asked to sit on the terrace. There were 2 questions. Has to write the code for it(in any language). After some time they announced the names of shortlisted students. Then came the F2F interview. It was a 2:1 interview. The interviewer was filled with rudeness. Enough to make the candidate nerves. They has the blank "GO TO HELL" expression the whole time. They told they would contact selected students.
