15-minute chat with HR.
A week-long coding test (which took at least a full weekend to complete), which I apparently did well in.
I was told that the team I had originally applied for did not actually have space for any interns, so I had a 30-minute phone chat with a director from a different team.
I think the level of investment from the company is hugely disproportionate compared to the investment that they ask candidates to make. The people I talked to over the phone seemed like they'd rather be anywhere else and were surprisingly unwilling to take/answer questions. This was an extremely disappointing experience because I feel like I was not given fair consideration for the role.
