• Algorithms Test (x2) - I definitely had two, though they may have had different names. Just blitz some LeetCode as practice, and you'll be fine.

• Data Structures - Know how array lists, red-black trees, hash tables, and linked lists work. All pretty standard.

• Systems Design - This was done verbally, which was a bit odd. It exposed that their infrastructure is stuck in the dark ages.

• Cultural Interview - I got hard-sold the job.

I was asked about data structures such as array lists, linked lists, hash tables, concurrent hash tables, and red-black trees. With knowledge of these, you should be fine for the algorithms questions too.

LeetCode shows what GS most frequently asks. I received an easy/medium question, then a hard one.
