I applied online. The process took one week.

HR was kind and forthcoming. The technical questions were fair and relevant. The interviewer knew what he was talking about and gave a good pitch for the company. It sounds to me like a healthy and happy place to work if you can handle the small startup life and pace.

How to handle a known number of tasks that need to access the same resource without using any kind of semaphores or mutex. Each task should be blocked until the resource has been updated by them.
