I applied online. The process took 1 week. I interviewed at Proton Technologies (New York, NY) in May 2018
Interview
Responded to a listing on LinkedIn. Contacted by HR to fill out a more in depth application. Contacted next week for interviews. Initial contact, general questions. Tech screening by tech lead, and then a one on one with the CEO. Got an offer letter in two days.
I applied online. I interviewed at Proton Technologies (Geneva) in Feb 2017
Interview
One first interview on site to test my logical skills, and one project interview to be developed in PHP. Good part is they pay for your time (through paypal), but still it is pretty time consuming and the project interview was very unclear.
