I applied online. Took them 3 weeks to follow-up with an invitation to a phone interview. The interview seemed to have gone well. We talked about the company, the role, and also about my past experiences. I tried to talk about all my past experiences with their product (RStudio's IDE in particular) and also my experiences with Python in the context of data engineering and data science. I also have let them know that I have an extensive portfolio with many notebooks (R notebooks and also Jupyter notebooks). She promised me an interview asap. "Possibly this very same week" she said. Unfortunately, she's a bald-faced liar. I didn't hear from her until about 3 weeks later when I received an email saying that the position had already been filled. I dodged a bullet to be honest. Who uses RStudio these days? You don't see younger data scientists/analysts using R any longer (I don't use RStudio in at least two years, professionally). They even changed their IDE to support Python notebooks, which is only a feeble attempt to delay their likely obsolesce.
