HR calls for an interview and asks to give an interview in the next 1 hour. They will ask you to open your camera but won't open theirs. If you'll ask them to open the camera they'll say we are the interviewers we don't do that. Now the questions were all theoretical. Difference bw soft assert and hard assert(they will ask for definition). JDK and JVM. Grow up! You are not hiring freshers.
