The interview process is long but very clear and you understand the process from the beginning. From application to offer, the process was exactly two months for me. After the Assessment Centre they say it could take two weeks to give you an offer - it was exactly two weeks for me. The longest two weeks but it was worth the wait.
First I had a screening call with a Salesforce recruiter three days after I applied for the position, followed by a call with another Salesforce recruiter eight days later. The first call consisted of basic interview questions, why you want to work at Salesforce, etc. The second call was more focused on Salesforce products and customers, however it wasn't a test. The recruiter spoke for a long time about the products and customers. They wanted to tell you how to prepare for the next stage. Both recruiters were very friendly and helpful.
The second stage is a video call with the managers. It was quite relaxed, they wanted to get to know you. These are all of the questions they asked me as well as some more related to my experience:
1. Why do you want to work in sales?
2. What do you want to get out of sales?
3. Why Salesforce?
4. What is you understanding of the BDA role?
5. What other companies and roles are you applying to?
6. What is your criteria for choosing one company over another?
7. What do you bring to a team, what is your role?
8. A time when you received negative feedback, how did it make you feel?
The third stage is the assessment centre - you go to Salesforce for a day, you get to meet the team and other applicants.
A week before the Assessment Centre you get sent a case study which you have to prepare a presentation on. On the day you will be put into a group with two others and present to the company in the case study. It is an easy case study, it is not designed to trip you but to showcase your knowledge of Salesforce products and to see how you work in a team.
We had to be there for 9am, but the day began at 9:20. There was a presentation welcoming us, showing us the plan for the day and telling us about the role and the career progression path. At 10am the assessments began. Half of the applicants would have the case study first, the other half had the interviews first. Then a 45 minute lunch break and back to interviews/case studies.
We had two interviews: one seemed to focus more on your work and academic experience and why you wanted to work in sales. The other interview seemed to focus more on your interests and hobbies. These were very relaxed interviews. In the interview time block, you were also given a tour of the office by current BDAs. You can ask them anything about Salesforce, the role, the office - if you have any burning questions you don't want to ask in an interview this is the time to.
The case study block: you're put into teams of three and you are given 45 minutes to discuss your findings and to prepare your presentation to the prospects. You are in a meeting room for this with two Salesforce employees. They assess your teamwork skills while you are preparing the presentation. This is a group task so they want to see if you can listen to other people and take their opinions on board, they don't want someone who is bossing the group or not contributing at all. Then you are given 20/25 minutes to present. The Salesforce employees are now your prospects - they know nothing about Salesforce, you need to sell it to them. They will ask you questions throughout the presentation, not at the end.
The day finished at 3:30. It was an enjoyable day and you really get a feel for the company and the culture.
