I applied through university. The process took 1 week. I interviewed at EF (Education First) (Cambridge, MA)
Interview
The people were all very friendly, making for relatively low-stress first- and second-round interviews. The whole process (first round, second round, offer) took one week, and they were willing to expedite everything because of a deadline I had for another job offer. All-in-all, a very positive experience.
