From start to finish, the process took a month and a half (due to rescheduling)
After applying online, the recruiter contacted me within the week to schedule the initial screening. The recruiters were helpful and took the time to guide me through the process. The only negative was that the initial contact was scheduled with a person in the US time zone (while I'm in Europe) for a role in Europe.
The next stage was an interview with the Manager for the Customer Success team, who is hiring. The discussion was easy. We talked about my experience, the team, the company, etc.
The next stage was a panel interview roleplaying a CSM presenting to clients based on the received brief. The panel consisted of a Senior team member, the Manager of the Customer Success team, and the Director of the Customer Success department. The panel asked questions about my experience, apart from their engagement in their roleplay. The only difficulty was questions specific to their platform.
The final feedback came roughly 2 weeks after this stage. It was negative, however, detailed enough to know people were paying attention.
The main reason for the negative response was wanting someone with "deeper knowledge of data ingestion methods and a more comprehensive understanding of the Braze platform". Realistically, while the first part may be somewhat reasonable, the second part would be something you would gain either as a Braze client or employee.
