Applied online, get fast reply on the same day or the next day. The 1st interview was incredibly short, more or less 5 mins. Then you will for sure get a 2nd interview, my advice is: DON'T GO! Seriously! You will regret not taking my advice. In the second interview (a job shadow), they will not tell you or even hint of what it is or how it is going to be like. Anyway, one of their reps will take you to somewhere far away from the city, like Cambridge. Even if you regretted in the middle of job shadow, you cannot come back to the city by yourself. You will spend the whole day outside, in the freezing weather from noon until 8/9pm. Then they will drive you back to the office around 10pm. The other candidate and I were shocked when we arrived. Then realized that all they do is to knock on people's door one by one on the street to ask for donations. The whole day is a waste of time and freezing cold outside.
