In the beginning, it was incredibly boring. It stepped up near the end to become more challenging and/or entertaining.
I enjoyed learning the ins-and-outs of an AGILE workflow, as well as what a real development environment is like to work in. The work I was doing was mostly odd-job support tasks: things like creating monitoring dashboards with Splunk. I never did any actual programming.
I wish that I had had more time doing *programming* instead of busywork.
I think I could have been guided a little bit more in the beginning, since there is a lot to learn in this position about the things we are working on. There were so many acronyms, and I was never *trained*, I just had to ask whenever some crazy new acronym showed up.
It was great to get to know my small team, but I didn't get the chance to meet most of the other people sharing my office. There were plenty of events to do so, but I wasn't here long enough to get comfortable with them.
I did not have a job posting. I was reached out to specifically. There was less legitimate programming than expected/desired.
Be ready to be independent. A foundation of self-discipline and an understanding of the AGILE methodology will be extremely helpful.
