I applied online. The process took 1 week.

First of all, note that most of the company reviews posted here are fake. They are almost all posted within a 24-hour time window and all are 5-star. I was initially asked to do an online assessment (both behavioral and technical) on their platform. Please note that this is their final product: a hiring interview tool. After I completed the test, I was asked to prepare for a LeetCode hard question in a half-hour interview I was scheduled for. The communications were so unprofessional that I cancelled the interview and I didn't waste my time on it.

For example, I got a message on WhatsApp asking for my resume. I was told they had it on their platform but it was too difficult for them to download it and move it. I think the positions are fake and they use potential candidates to collect data for their hiring product. The process was unusually unreasonable and unprofessional and I'm sure this cannot be for a real opening.
