This has been my most negative work experience so far, which luckily only lasted 5 weeks. I saw absolutely no opportunity for professional growth, as the Data Science team was reluctant to use Python and sklearn, and instead only used packages available in R.
This then has an impact on the problem definition too: the questions that cannot be solved with R will not be asked.
If you are looking to acquire the skills of building an automated data pipeline, apply cutting edge machine learning techniques with Python, sklearn and Tensor Flow, learn unit testing and hyperparameter tuning, then this is definitely not the right place in my opinion.
