Salesforce Software Developer Internship interview questions

On campus interviews were given immediately after the info session. It was the first round of interviews and they basically asked all technical questions, only the first question was behavioral. The last part of the interview I had to do was solve a technical problem like find the missing number in a list.

2 Rounds : 1st round was a phone interview discussing resume and a couple coding questions. Didnt have to write code but just explain thought process and how I intended to solve. 2nd round: They fly you out to San Francisco. Unfortunately I couldnt make it to any of the days, So I was scheduled 2 back to back video call interviews. First interview required answering a coding question, 2nd one was behavioral.
