I applied for the position through LinkedIn. It took less than 2 days to sent me an email and ask to update my calendar to do HR Interview. They Have arranged the interview in less than a week. However, they never called me (They disappeared)!!! I emailed them to follow up, but they never bother to response!!! Very Unprofessional. Waste of time!

There were a couple of emails then a short code test and two phone / Skype interviews (and a background check). After that they asked for an interview at their office which started early morning and took all work day. Met with a handful of their team, answered a bunch of tech questions. After the all-day interview, they did the "thanks for coming, we'll be in touch soon". Waited weeks for a response and not a single response came -- no phone calls, no emails. Emailed them about a month after and still no response. Very unprofessional and a huge waste of time.
