I applied online. I interviewed at City Year (Boston, MA)
Interview
You submit an online application then they follow up with a screening "conversation" through skype. If you pass that they do a 45-60 min interview over the phone. The longer phone interview if full of tough behavioral questions, the shorter interview is more straight forward. I think you have a better chance of getting the position if you opt for "serve where most needed."
Interview questions [1]
Question 1
How would you design a student curriculum? Tell me about challenges you faced working in a group?
Very simple. Quick virtual interview and pretty simple questions. Research their values and what not and you should be good to go. As far as I remember it was a single interview and decision is relatively soon after that.
Really friendly and welcoming. Try to make it as comfortable as possible and share about the work they do. They want to ensure applicants are making the right decisions and that they assess the values.
I applied through university. The process took 2 weeks. I interviewed at City Year
Interview
Done over zoom and not an overly long process interviews are usually conducted by the IM for a school in the city you are applying for but if you have a pulse you should be fine
