The interview first start by giving you a take home test problem to review, Then the onsite interview comes with 3 in person round, two with team member, and one with the team manager. One interviewer was very unprofessional and condescending, has bad attitude on answers that he wasn't expected. What's even worse is he even scheduled another extra virtual round with me only to spend extra time grinding on the only topics he knows. The final round was interviewed by the CTO, and ironically he also brought the same condescending attitude investigating my company's workflow and no respect of my work experience. The entire process was lengthy and complete waste of time.
