I did not get to the phone interview but I will describe the 3 parts I did: 1. are you 18 and willing to move to Memphis? If yes--> part 2 2. IQ test of sorts. 50 questions in 12 minutes. go fast. if pass->part 3 3. coding challenge. you really need to know Java to pass this. I did it in Python but not a passable score. from company website FAQ: "Do I have to have prior programming knowledge? A prior fundamental programming knowledge is best, but certainly not required if you can pass all the onboarding steps." -okay. so if you don't know Java 8 you will absolutely fail the coding challenge. I suspect that since the bootcamp is only 8 weeks long (most bootcamps are 3-6months) they are trying to get people with coding experience so that there is a lower drop out rate possibly? Overall a good experience. I didn't get into the Apr 9th session but will be reapplying to May 17th session. Studying a ton of Java in the meantime.
