Typically 4-5 stages. 1st stage is phone screening. 2nd stage is when you get asked technical questions. You get a homework which you would present and answer follow up questions during the 3rd stage. 4th stage is with the CEO. Final stage is to discuss your offer.

Very odd process with multiple interviews that resulted in being ghosted. I read another review from someone else who was ghosted at the same time and realized that I was not alone. I was interested in the company because of the philosophy they had as the salary was considerably less than what the market paid for what they expected. However, I thought that environment was more important than money. I had three interviews and expected to hear back within a week or so about the result. Nothing - no sorry you didn’t get it, nothing. That said a lot to me about the culture and I’m happy I didn’t get it as I don’t want to work in a place that doesn’t respect people enough to not ghost them.
