I had a great interview experience.

The process was transparent and well-organized, starting with a challenging LeetCode-style coding question, followed by a creative feature design task. The third interview was a high-level service design discussion, which was particularly insightful. The final interviews with management and HR were similar and gave me a clear understanding of culture and growth opportunities.

Overall, every question was relevant, and the experience left me with a very positive impression of the company.

You should implement the mentions feature in their system.
