I learned an enormous amount and felt incredibly well-treated. The culture was very good.
One coworker began paternity leave while I was there and our boss definitely made it clear that she wanted him to know that he had every right to take a full leave, but that she would really like it if he could return sooner than planned. I wouldn't say that he was truly pressured to return early, but her support for him could've been a bit more wholehearted.
The other major weakness in my personal experience was that my internship was a bit chaotic because it was unofficial. My status occured because I was not a current student, but rather started my career late. I appreciate 100% that the company made an exception and specially created the temporary position specifically to benefit me, but I think it's worth ackowledging that they could've organized it a bit better. At times, I felt that those supervising me were perhaps overly kind for my good and may not have always given me fully honest feedback.
In spite of those very minor issues, I would recommend this employer enthusiastically to anyone and would gladly accept a position there in the future.
