Applied a month before getting a call from HR. Recruiter asked me preliminary questions about my resume. They then expedited the whole process within 2 week; 4 interviews with 2 department, which was understandable if they needed to fill the position ASAP. Pushed me to interview round 2&3 during my vacation out of the country. Did not receive any updates after the 4th interview, no rejection emails. Completely ghosted.
