First round phone screen. Onsite Skype interview with engineers afterwards. HR is VERY EFFICIENT in coordinating. Applied online and get phone interview invitation one day after, they gave me positive feedback and had me scheduled for onsite Skype interview a couple hours later. I interviewed with four software engineers. The interviewers are all very friendly and give you hints to get optimal solution. I could tell they really love their job and are willing to contribute to the team. Company culture is great and offers much flexibility and space to grow. Overall very positive experience.

HR contacted me to schedule a phone screen with hiring manager. Next week, the hiring manager skype me, asking questions about my resume and background, the coding question was not very difficult as long as you know basic data structure and algorithms. One day after that, HR told me that they want to schedule an skype onsite interview with three engineers. The skype onsite was similar to the previous one. I would say that all the interviewers are very nice to answer all my questions about the company and help you to solve the problem when I got stuck. HR is very efficient and extended me an offer two days after the skype onsite.
