Deloitte Consultant Salesforce interview questions

First phone screening interview was easy. What is the difference between a workflow and a trigger? That type of questions.. On site interviews are little challenging. was interviewed by three people. the first one was easy..Basically asking about my background. Second one: I was given a problem and I had to suggest an approach. third one was though.. What are the SF APIs?

It was good experience based on certain rounds. There were total 4 rounds. Recruitment team was very cooperative in terms of handling candidates and food was provided for all. It was overall nice experience.
