One thing that stood out right away was how courteous and efficient the overall interview process felt from start to finish. The steps moved quickly and the in-person portion was challenging, but it didn’t feel disorganized—it felt like the role itself was a good match for the mix of skills I already had, while still leaving room to learn new things.
In my case, it came together as a relatively simple process with a phone interview shortly after I applied, followed by an office interview later in the week. The whole structure made it easier to stay focused because there weren’t too many stages to wonder about.

I was referred through a career transition firm, and from there I worked with the recruiter to get a phone screening and then a follow-up interview. What really impressed me most was how fast the organization moved—everything seemed to progress at high speed.
I also noticed the structure of the teams and management levels: the teams were small, and there were enough layers of management to support things without making day-to-day interactions feel cumbersome. The overall vibe was energetic—never really dull.
