Mercado Libre Backend Developer interview questions

The process lasted over 2 months and involved 5 interview rounds (Recruiter, Senior Developers, Project Leader, Project Manager, and Technical Leader), plus a technical challenge (basic API). Communication was poor; the process went into an unexplained standby period, and I only received updates after I took the initiative to follow up. Despite the significant time investment and reaching the final stages with leadership, the feedback provided was a generic rejection template. There is a clear lack of transparency regarding the timeline and a disappointing disregard for the candidate's time.
