Mindtree Interview Questions & Answers
Q1. What is the time complexity of common sorting algorithms?
AptitudeModel Answer:
Bubble Sort: O(n²) avg/worst, O(n) best. Selection Sort: O(n²) always. Insertion Sort: O(n²) avg, O(n) best. Merge Sort: O(n log n) always, O(n) space. Quick Sort: O(n log n) avg, O(n²) worst, O(log n) space. Heap Sort: O(n log n) always, O(1) space. For interviews: Merge Sort (stable, predictable) and Quick Sort (fast in practice) are most important.
Q2. Explain the concept of recursion with an example.
TechnicalModel Answer:
Recursion is when a function calls itself to solve a smaller subproblem. Every recursive function needs: (1) Base case — stops recursion; (2) Recursive case — problem shrinks toward base case. Example: factorial(n) = n * factorial(n-1); base case factorial(0) = 1. Key risk: stack overflow if base case is missing or n is too large.
Q3. Check if two strings are anagrams.
CodingModel Answer:
```python
from collections import Counter
def are_anagrams(s1, s2):
return Counter(s1.lower()) == Counter(s2.lower())
# Without Counter (sorted approach):
def are_anagrams_v2(s1, s2):
return sorted(s1.lower()) == sorted(s2.lower())
```
Counter approach: O(n) time. Sorted approach: O(n log n) time.
Q4. What is your greatest strength?
HR / BehavioralModel Answer:
Pick a strength relevant to software development and prove it with a specific example. Good choices: fast learner, problem-solver, attention to detail. Format: 'My greatest strength is [X]. For example, during my final year project, I [specific situation] which resulted in [outcome]. I'd bring this same approach to LTIMindtree projects.'
