Pathetic process. It takes infinite time for them to reply or send a feedback. They say that they are a startup and they do things fast but their hiring process is not at all suitable for international students. Took me more than 2 months for the whole process. They mentioned 2 years of experience in JD as a requirement and later will expect to lead the team once onboarded which can be a criteria to select a candidate in the mid-way process. No particular fixed set of rounds. They will ask for your time until and unless you are exhausted.
