    Some users may find the difficulty of certain challenges to be either too high or too low, making it harder to find problems that are appropriately challenging for their skill level.
  • Limited Career Development Features
    The site focuses primarily on coding challenges and lacks extensive resources for job placement or career development compared to other platforms like HackerRank or LeetCode.
