Salesforce Software Engineer interview questions

The process started with a technical phone conversation with one of the managers. There was a 3-hour programming project in the second round. After that, I went for the onsite interview at Salesforce headquarter in San Francisco. The company has nice office and the interviewers were friendly and knowledgeable. There were 3 technical rounds and a lunch interview with the team's manager. Each technical round had two engineers. The questions were not difficult but had a broad coverage. They covered everything from front-end to back-end because it was a full-stack position. After the onsite, I got a callback to do another phone screen with the Principal Engineer. I got the offer by the end of that day.
