Summarized question:
Clear

Tell me about a time you had to deal with a difficult team member. How did you handle it and what was the outcome?

Answer:
Situation: On my previous team, a senior developer was consistently missing sprint commitments, which was creating a bottleneck for the rest of the team and putting our quarterly release at risk. Task: As the tech lead, I needed to address the delivery gap and get the team back on track — ideally without escalating to management, since

Summarized question:Clear

Implement merge sort and explain the time complexity.

Answer:
Merge sort uses divide and conquer — split the array in half recursively, then merge sorted halves back. Time complexity is O(n log n) in all cases because we always split into halves (log n levels) and merge takes O(n) at each level. Space complexity is O(n) for the temporary arrays during merging.
