Technical Interview Questions & Answers
Top 15 Most Asked Technical Questions
1. Introduce Yourself
Give a brief introduction including college, degree, and coding competition ranks.
2. What are Search and Sort Algorithms?
Search Algorithms: Find elements in data structures (Linear Search, Binary Search)
Sort Algorithms: Arrange data in specific order (Quick Sort, Merge Sort)
3. Write Bubble Sort Code & Time Complexity
// Bubble Sort in Java
for(int i = 0; i < n-1; i++) {
for(int j = 0; j < n-i-1; j++) {
if(arr[j] > arr[j+1]) {
// swap
int temp = arr[j];
arr[j] = arr[j+1];
arr[j+1] = temp;
}
}
}Time Complexity: O(n²)
4. Difference Between HashMap and Hashtable
| HashMap | Hashtable |
|---|---|
| Non-synchronized | Synchronized |
| Allows null keys | Does not allow null keys |
| Fast | Slow |
