Applied on Hackerrank. The whole process took about 3 weeks. I had a phone screen, a virtual onsite, then separate Skype calls with VP of Engineering, CPO, and CEO. Interview questions are of medium difficulty. Everyone I've talked to are smart and nice. The hiring manager called me several times before my interview with the CEO to answer questions I have about the company and prepared me for the interview. I accepted the offer because I trusted CEO's ability to lead this company to success, I believe the product will make a huge impact in the corporate world, and I like to work with the people I met during the interview process.
