Pros
They offer the opportunity to learn and work with leading technologies in the industry: Python, AWS, Docker, SalesForce. The provide a monthly "Invest in Yourself Day" when you can do pretty much whatever you want or need.
Cons
They were not clear about the position for which they were hiring me. I thought it was a position as Senior Java Software Engineer when in reality it was Principal Python Software Engineer. It was a steep learning curve to get up to speed with Python, Spark, and AWS. I didn't mind the challenge, even putting in a couple of hours every Friday evening to study for AWS certification. But I found it unfair that during the performance review process, I was compared with other Principal Software Engineers with much more experience using Python and AWS. My immediate manager was forced to put me on a PIP with the intention of terminating my employment. (Apparently, management had set a target of 15 percent for bad performance reviews, based on stacked ranking. The PIP is just a formality after the managers have already made up their minds to get rid of those targeted in the bottom 15 percent.) I would never have accepted the job offer if I had known what the real deal was with C1's work culture.
