Oracle SDE (Software Development Engineer) Interview Questions and Answers

I am currently working as a Software Development Engineer with expertise in web development and cloud computing.

• Proficient in programming languages like Java, Python, and JavaScript

• Experience in developing and maintaining web applications using frameworks like React and Angular

• Knowledge of cloud computing platforms such as AWS and Azure

• Familiarity with database management systems like MySQL and MongoDB

• Strong problem-so

BST search time is O(log n) on average, but can be O(n) in worst case.

• BST search time depends on the height of the tree

• On average, height is log base 2 of n

• Worst case is when the tree is unbalanced and height is n

• Example: searching for a value in a balanced BST with 1024 nodes takes at most 10 comparisons

I have a Bachelor's degree in Computer Science.

• Bachelor's degree in Computer Science

• Completed courses in programming languages, algorithms, data structures, and software engineering

• Participated in various coding competitions and hackathons

The time complexity of the program is O(nlogn).

• The program has a divide and conquer algorithm.

• The program has nested loops.

• The program has a recursive function.

Design an algorithm with less time complexity.

• Use efficient data structures like hash tables, binary trees, etc.

• Avoid nested loops and recursion if possible.

• Try to optimize the code by reducing redundant operations.

• Use dynamic programming to solve complex problems.

• Consider parallel processing for large datasets.

• Use built-in functions and libraries instead of writing custom code.

• Profile the code to identify bottlenecks
