I submitted my resume, then had a chat with the big boss first then spoke with the lead for the team I was going to join. Had to do a writing test after that.

Doesn't follow the initial call/whatsapp from HR, but instead they contact you via direct message on LinkedIn to set up the meeting. First call is with the director, then there's a writing test. Although the deadline was given as end of the week, they sent a chaser after two days; after the submission of the test, the email correspondence slowed considerably. Unclear whether they are shorthanded or just lost track of candidates.
