Two Interviews, one technical, one personality assessment. The technical interview was primarily focused around theoretical knowledge about machine learning models. So just learn by heart all the theory. The personality interview was just straightforward, all the cliche questions.

Applied online. HR contacted me and required me to submit a complete CV without any gaps (we are living in the 21st century -- not every experience is relevant to the job). I complied and took half a day to look up and summarize all my experiences since highschool. Almost immediately after my resubmission, the position was no longer available and I received a decline. It was probably an internal hire, but why go through the lengths of making a prospective candidate jump though extra hoops. Could have just taken my application and rejected given that I probably had no chance anyways. Absolutely respectless.
