IBM Entry-level Software Developer interview questions

Passed OA and had a guru interview. My most familiar language is Java and the interviewee kept asking me Javascript questions for about forty minutes. It seems that the interviewee knows well about frontend but the position which I was applying is the general one. I am NOT applying for entry-level front-end engineer.

It's a four hours online interview. No one on the other side, three coding problems. All are easy. After half month, got the email from IBM to enter the next round of interview.
