Tip 3: Make projects.
Tip 1: Highlight your technical skills.
Tip 2: Include 2 to 3 projects in your resume.



Given a string, reverse the order of words in it.
Example:
Input: "DXC Technology is great"
Output: "great is Technology DXC"
Reverse Words in a String:
Algorithm:
1. Split the input string into an array of words using space as the delimiter.
2. Reverse the array of words.
3. Join the reversed array of words into a single string with space as the separator.
4. Return the reversed string.



Given an array of integers, return indices of the two numbers such that they add up to a specific target. You may assume that each input would have exactly one solution, and you may not use the same element twice.
Example:
Input: nums = [2, 7, 11, 15], target = 9
Output: [0, 1] (since nums[0] + nums[1] = 2 + 7 = 9)

Algorithm:
1. Initialize an empty dictionary to store the indices of numbers encountered.
2. Iterate through the array.
3. For each element `num` in the array:
- Calculate the complement as `target - num`.
- Check if the complement exists in the dictionary.
- If it does, return the indices of `num` and its complement.
- If it doesn't, add `num` to the dictionary with its index as the value.
4. If no solution is found, return an empty array or a message indicating no solution exists.



Given a binary tree, return the inorder traversal of its nodes' values.
Example:
Input: [1, null, 2, 3] 12/3
Output: [1, 3, 2]
Algorithm:
1. Initialize an empty list to store the inorder traversal result.
2. Define a helper function to perform recursive inorder traversal:
- If the current node is not null:
- Recursively traverse the left subtree.
- Append the value of the current node to the result list.
- Recursively traverse the right subtree.
3. Call the helper function with the root of the binary tree.
In this round, you might be asked about the projects listed on your resume, questions related to Database Management Systems (DBMS), and Operating Systems (OS).
Certainly! Here's how you might approach answering those questions:
1. Projects on Resume:
- Begin by briefly describing each project you listed on your resume, highlighting the problem you aimed to solve, the technologies or languages used, and your role in the project.
- Provide specific details about the features, functionalities, and any challenges you encountered during the project.
- Emphasize any innovative solutions you implemented or any significant outcomes achieved.
- Be prepared to answer follow-up questions about the technologies used, design decisions made, and the overall impact of the project.
2. DBMS Questions:(Link)
- If asked to write an SQL query, start by understanding the requirements clearly. Ask clarifying questions if needed.
- Based on the given scenario or query requirement, formulate the SQL query using appropriate syntax and clauses such as SELECT, FROM, WHERE, GROUP BY, ORDER BY, etc.
- Ensure that the query addresses all aspects of the problem statement and produces the expected results.
- Consider optimizing the query for performance if applicable, by using indexes, avoiding unnecessary joins, or optimizing the WHERE clause.
- Be prepared to explain your query, including how it retrieves the desired data and any potential limitations or alternative approaches.
3. OS Questions:(Link)
- For Operating System questions, start by understanding the fundamental concepts related to the question, such as processes, threads, memory management, file systems, etc.
- Answer the question methodically, breaking down complex concepts into simpler explanations.
- Provide examples or use cases to illustrate your points and demonstrate your understanding.
- If asked to solve a problem or write pseudo-code related to OS concepts, approach it step by step, considering factors like resource allocation, synchronization, and concurrency.
- Be prepared to discuss real-world applications of OS concepts and their significance in modern computing environments.
Overall, in both DBMS and OS questions, demonstrate your understanding of core concepts, problem-solving skills, and ability to articulate your thoughts clearly. Practice writing SQL queries and solving OS-related problems to become more confident in handling such questions during interviews.
