Be ready to go over:

• Object-Oriented Programming (OOP) – Understanding classes, objects, inheritance, and encapsulation.
• String Manipulation – Reversing strings, finding duplicates, and parsing text.
• Basic Data Structures – Working with arrays, lists, dictionaries, and sets.
• Advanced concepts (less common) – Time complexity analysis (Big O), sorting algorithms, and memory management.

Example questions or scenarios:

• "Write a Python script to check if a given string is a palindrome."
• "Explain how you would use class inheritance to model different types of users in a test automation framework."

Relational Databases & SQL

QA engineers must frequently validate data integrity at the database level rather than relying solely on the user interface.

Be ready to go over:

• Basic SELECT Queries – Retrieving specific data using filters and sorting.
• Table Joins – Combining data from multiple tables using INNER, LEFT, and RIGHT joins.
• Data Aggregation – Using functions like GROUP BY, COUNT, and SUM.
• Advanced concepts (less common) – Subqueries, nested joins, and database indexing strategies.

Example questions or scenarios:

• "Write an SQL query to find the second-highest salary from an Employee table."
• "How would you verify that a frontend form submission successfully populated the correct relational tables in the backend database?"

As a QA Engineer at Itlize Global, your day-to-day responsibilities will revolve around ensuring the delivery of high-quality software solutions. You will be embedded within a project team, working closely with developers, product owners, and clients to understand requirements and translate them into actionable test strategies.

You will be responsible for authoring detailed test plans, designing manual test cases, and executing them across web, mobile, and backend platforms. When defects are discovered, you will log them with precise steps to reproduce, collaborate with developers to resolve them, and perform regression testing to ensure no new bugs were introduced. Additionally, you will write basic SQL queries to validate backend transactions and data transformations, ensuring that the database layer operates in harmony with the user interface.

To be competitive for the QA Engineer role at Itlize Global, you should possess a solid foundation in software testing methodologies combined with practical technical skills.

• Must-have skills – Strong knowledge of software testing life cycle (STLC) and software development life cycle (SDLC).
• Must-have skills – Proficiency in writing detailed test plans, test cases, and bug reports.
• Must-have skills – Basic programming knowledge (preferably Python) and a strong grasp of Object-Oriented Programming (OOP) concepts.
• Must-have skills – Competency in SQL for executing relational database queries.
• Nice-to-have skills – Experience with test automation tools such as Selenium WebDriver or PyTest.
• Nice-to-have skills – Familiarity with API testing tools like Postman.
• Nice-to-have skills – Experience working in an Agile/Scrum development environment.

Q: How difficult is the QA Engineer interview at Itlize Global? The interview difficulty is generally rated as average to easy, depending on your background. While the coding and SQL questions are straightforward and cover foundational concepts, you must prepare thoroughly for the logical aptitude tests and basic programming questions.

Q: What programming language should I focus on for the technical round? Python is highly recommended. Interviewers frequently ask about Python basics, OOP concepts (like classes and objects), and basic string manipulation. If you are more comfortable with Java, you can use it, but Python is widely preferred.

Q: Does the interview process involve an aptitude test? Yes, candidates often report facing logical and verbal aptitude questions during the initial screening stages. These tests evaluate your critical thinking and analytical reasoning skills before you advance to the deep technical rounds.

Q: What is the typical timeline from the first interview to the final offer? The entire process can take anywhere from one to three weeks. After successfully passing the technical and managerial rounds, you will be asked to submit documents to HR, after which a final salary discussion and offer call typically occur within a week.

• Master OOP Basics: Do not overlook basic Object-Oriented Programming concepts. Be ready to explain classes, objects, and inheritance with clear, real-world analogies.
• Practice SQL Joins: Ensure you can write clean SQL queries on the fly. Focus heavily on INNER JOINs, LEFT JOINs, and basic aggregate functions.
• Be Scenario-Ready: When asked to design test cases, structure your response logically. Start with high-level functional tests, move to negative scenarios, and finish with edge cases and performance considerations.
• Prepare Your Documents: Have your academic and professional documents ready for submission immediately after the managerial round to speed up the HR onboarding process.

Securing a QA Engineer role at Itlize Global is an excellent opportunity to accelerate your career in quality assurance and software consulting. By mastering fundamental manual testing concepts, brushing up on your Python and OOP basics, and practicing SQL queries, you will position yourself as a highly competitive candidate.

Remember to approach every problem systematically. Whether you are writing a test plan for a navigation application or solving a string manipulation coding challenge, the interviewers are assessing your logical process and communication skills just as much as your final answer.
