I applied through an employee referral. The process took 2 weeks. I interviewed at Kumon (Dublin, CA) in May 2015
Interview
You'll be taking a quick test then you get to be interviewed right afterwards. They ask you your availability etc. I didn't have to wait for a callback. They gave me the job right away.
No real interview process, easy to get through. I just contacted the manager of the Kumon I worked at, and I got the job in a couple days. Great for high school students.
Very straightforward and easy, went over previous jobs/positions but does not need to be relevant. Just need to elaborate why you want this position. There was not much needed to get this role
The interview process was not difficult at all. They asked very easy and basic questions that were not difficult to answer. I was basically hired on the spot, no stress at all.
