This post is contributed by Morgan Chen, a Salesforce QA Engineer with 9 years of experience in functional testing, test automation, and release validation across enterprise CRM implementations. I was laid off from a mid-sized SaaS company, where I had spent 5 years leading Salesforce quality assurance for a Sales Cloud and Service Cloud implementation. Over 3 months I went through 14 technical screens, including salesforce apex testing drills, Salesforce test automation exercises, and process-focused panel discussions. The 20 questions below come directly from those interviews, with the answers I gave and my honest read on what each interviewer was testing.
