Which platform is well-known for offering a variety of technical interview preparation questions?

HackerRank is widely recognized as a leading platform for technical interview preparation due to its extensive collection of coding challenges and interview questions that reflect the types of problems candidates typically encounter during interviews with tech companies. The platform allows users to practice coding in various programming languages, providing a hands-on approach to learning and reinforcing skills that are essential for technical roles. Additionally, HackerRank features a gamified experience with progress tracking and competitions that motivate users to improve their coding abilities.

In contrast, Coursera, Udemy, and Pluralsight primarily focus on offering courses that cover a wide range of educational topics, including programming and software development, but they do not specialize solely in technical interview preparation. While these platforms can provide valuable learning resources and courses taught by industry professionals, they do not have the same level of dedicated coding challenges or mock interview scenarios that HackerRank offers.
