Most DS jobs just need SQL and a bit of R. Don't overthink it.You're thinking entry level jobs for people with BA at most. That's not the job you're competing for with a PhD.
These guys have no idea. To get a PhD-level job since the pandemic, the standards have gone through the roof.
You need to be almost as good at python as a SWE, know SQL as well as a database engineer, and know stats as well as a recent stats grad at the masters level. And you have to know all of this on the spot.
