The recruiter reached out to me to start the process. There was one technical phone interview (standard 5-10 min intros, 30 min technical question, 5-10 min to ask questions) and then the onsite afterward. The onsite had three technical interviews that were an hour long each. In two of them, it was a 1 on 1 interview, and in one of them, it was a 2 on 1 interview. After the interviews, they served us lunch and gave a 30-minute demo of the product. If you passed the onsite, there was a hiring manager interview where they told me that it would be mostly behavioral with a little coding. This was a lie. The whole interview was coding, excluding the intros and asking questions at the end. The question was difficult as well, so I was kinda caught off guard.
