Salesforce Software Engineer interview questions

I was referred by a friend and Pardot's technical recruiter contacted me by email that same day to schedule a phone interview with him. The phone interview was straightforward and low stress. After the interview I was given a take-home coding exercise which didn't take more than an hour or two to complete. The exercise wasn't difficult by any means but the instructions and goal of the exercise were somewhat unclear and confusing. After I submitted my solution for the exercise I was scheduled for a 45 minute phone interview with an engineer. During the interview we had some brief introductions and I was asked to write an algorithm to solve a problem and unit test it over a shared screen. The problem they give is easy. Laughably easy. Anyone with even a slight amount of coding ability should have zero trouble with it. The rest of the time was spent with me asking various questions about Pardot and the open position. The final step was an on-site interview consisting of two rounds. Each round was an hour long with two interviewers in each round. The interviewers were a mixture of senior engineers and engineering managers. I was asked about my experience and about a few things from my resume. During the technical portion I was asked some basic SQL questions. I was given the schemas for some tables and asked to write a query that would get data out of them. I was also asked to write code to solve a problem which involved tree traversal. I was also given several design questions. Three days after the final interview the recruiter called to give me a verbal offer.

Typical tech programming interview like any other big company. The process took little over 2 weeks. I applied online and the recruiter contacted me. Set up phone screen. And 4-5 onsite interviews. Onsite programming test was conducted. This was something different than other companies. You get 2 hours to code and a problem statement along with expected input and output is given. They typically ask to code in java but if you can choose a different language if you are not comfortable in java.
