The entire process stretched over three weeks, which felt a bit longer than I had anticipated. It kicked off with a technical phone screen where I tackled a binary tree traversal question. The next round involved implementing masked multi-head self-attention for a transformer, which I had worked through on PracHub in preparation. The final stage was a system design question comparing DCN v1 and v2, followed by a discussion on A/B testing. Overall, the experience was straightforward, and I was pleased to receive an offer, which I happily accepted.
