I was interviewing with a company that had barely any customers and they were asking scaling questions with Spark, etc. The salaries they paid could barely hire a team capable of dealing with the complexities of Spark, so they asked, "what would you do."
I told them I'd buy another stick of RAM and scale vertically until I had more customers, and save money on staff in the meantime. The interviewer went cold, I didnt get the job.
