Onsite interview summary:

• Consisted of three coding rounds with some leadership questions, and one behavioral round that included system design.
• I completed all coding challenges successfully:
  • Solved a BFS question, designed a library with nested structures, and tackled a practical heap problem.
• Faced challenges during the system design round:
  • The hiring manager arrived late, leaving me with limited time for system design, and unexpectedly, data modeling was deemed irrelevant.
  • The final Q&A was brief, and when I asked job-description-related questions, the responses were hesitant and questioned for relevance.

Unfortunately, I was not selected for the position.

Update:

Code:

• BFS (min number of steps to take up or down till target)
• Library (items and nested items) and add generic filters based on item property
• Log parsing (optimized for memory)

Design:

• Parking lot
