The original call with the recruiter is just an introductory call.
Once you get past that, then you will have a proper first round with an engineer on the team. They will ask about you a bit and the biggest challenge you have faced recently. They will then have 2 leetcode rated easy questions.
Provided you make it past that step, the next step is a 2-day 5 hour final round interview (3-hours first day, 2 hours the next day). 1 leetcode hard and 2 leetcode mediums
Overall the interviewers were good and collaborative
