My interviewer was so friendly, it almost felt like a recruiting visit. Like everyone else says, the housing is very affordable and nice. The apt I saw had hardwood floors, and they let you paint things as you wish.
What impressed you negatively?
Nothing really. To be nit-picky, the facilities are older than I am used to. Also, there are very limited options for coffee, etc. around there. I really wanted a latte :)
What did you wish you had known ahead of time?
The Bronx has quite the spectrum of living conditions. I was freaked out by some areas I saw, but the neighborhood around AECOM is nicer.
