It was quite interesting. You go through a couple of stages which includes working on two tasks (front end and back end), algorithm section and final phone interview. As long as you know your algorithms, advanced js and can build a full-stack app with the mern stack, you are good to go.
I applied online. The process took 2 weeks. I interviewed at HackerBay in Apr 2018
Interview
It was a pretty straightforward process.
It started with a couple software tasks to solve, then we progressed to a Skype interview.
The interview consisted of two parts: software problems and personality questions.
Overall, it was a pretty quick process..
