I applied through an employee referral. I interviewed at Harvard University
Interview
Hiring is different depending on which course you are a course assistant for- in my case, I had taken the course I taught for my freshman year and was recommended to be a CA by the professor. In general you send your application to Oliver Knill within the department and selections are made from there. Typically there are no interviews required, and previous teaching experience is not a prerequisite.
Interview questions [1]
Question 1
Prove for the following set of conditions that there is a subsequence f_k(x) that converges to a continuous function f(x):
1. f_k(x) is an infinite sequence of functions from the interval [0,1] to the set of real numbers.
2. The sequence is uniformly bounded, i.e. there exists some R<infty s.t. |f_k(x)|<R for all x,k.
3. The sequence is equicontinuous at every x.
