"100% Common 😎! Virtusa Important Technical Question | Virtusa Online Assessment Test 2025 | Tekno UF"

Main Ideas and Concepts:

Virtusa Online Assessment Overview:
- Exam date: Starting 6th July (for 2026 batch).
- Exam is on-campus.
- Importance of knowing eligibility, exam pattern, and technical questions.
- Encouragement to subscribe to the channel for more related videos.
Eligibility Criteria:
- Minimum 60-65% marks in 10th, 12th, and graduation.
- Education gap should not exceed one year.
- Even if criteria not met, applying is recommended as skills can sometimes outweigh marks.
Exam Pattern:
- Total 80 minutes duration.
- 40 MCQs covering:
  - Networking
  - Data Structures & Algorithms (DSA)
  - Operating Systems
  - Cloud Computing, etc.
- 2 programming questions:
  - One normal coding problem.
  - One debugging/fixing code problem.
- Followed by a Group Discussion round.
- This year, exam conducted by Mercer Metal (not MCAT), which has a different pattern.
- Cutoff expected between 60-70%.
Important Technical Topics & Sample Questions:
- Data Structures:
  - Stack uses LIFO (Last In First Out).
  - Queue uses FIFO (First In First Out).
  - Time complexity questions:
    - Binary Search worst case: O(log n).
    - Linear Search worst case: O(n).
    - Best case for both: O(1).
- Coding Debugging Example (Java):
  - Code: int x = 5; System.out.println(x++ + ++x);
  - Explanation of post-increment and pre-increment.
  - Correct output: 12 (common mistake is 13).
- SQL Questions:
  - Command to remove a table: DROP (not DELETE).
  - DELETE removes rows but keeps table structure.
  - Sample query: SELECT COUNT(*) FROM employee WHERE salary > 550000;
    - Returns count of employees with salary > 550,000.
- Operating System Questions:
  - Purpose of OS scheduler (quiz question asked).
  - Scheduling algorithm with starvation-free execution: FCFS (First Come First Serve).
- Networking Protocols:
  - Secure HTTP communication protocol: HTTPS (HyperText Transfer Protocol Secure).
  - FTP: File Transfer Protocol.
  - SMTP: Simple Mail Transfer Protocol (for sending emails).
  - TCP: Transmission Control Protocol.
  - DNS stands for Domain Name System.
- Recursion:
  - If a function is called recursively 5 times, it is stored 5 times in the call stack.
- Operator Precedence (Programming):
  - Example: print(3 * 3 ** 2)
  - Exponentiation (**) has higher precedence than multiplication.
  - Result: 27.
Additional Advice:
- Few resources available online for Virtusa full preparation.
- Recommended website: topmail.technology/technology for:
  - Technical questions.
  - Coding questions.
  - Interview questions.
  - Mock tests.

Detailed Bullet Points:

Eligibility:
- 60-65%+ in 10th, 12th, graduation.
- ≤1 year education gap.
- Apply even if criteria not met; skills matter.
Assessment Pattern:
- 40 MCQs (Networking, DSA, OS, Cloud, etc.).
- 2 coding questions (one normal, one debugging).
- 80 minutes total.
- Group Discussion post-technical round.
- Exam conducted by Mercer Metal this year.
- Cutoff: 60-70%.
Key Topics & Sample Questions:
- Data Structures: Stack (LIFO), Queue (FIFO).
- Time complexity: Binary Search O(log n), Linear Search O(n).
- Java code increment operators output explanation.
- SQL commands: DROP vs DELETE.
- SQL query for counting employees with salary condition.
- OS scheduler purpose and FCFS algorithm (starvation-free).
- Networking Protocols: HTTPS, FTP, SMTP, TCP, DNS.
- Recursion call stack storage count.
- Operator precedence in expressions (exponentiation before multiplication).
