OSP Labs Senior Engineer Interview Questions, Process, and Tips

I ensure security at application level by implementing secure coding practices and regularly testing for vulnerabilities.

• Implement secure coding practices such as input validation, output encoding, and proper error handling

• Regularly test for vulnerabilities using tools like OWASP ZAP and Burp Suite

• Implement access controls and authentication mechanisms to ensure only authorized users can access sensitive data

• Encrypt se...read more

Database passwords should be stored securely using hashing and salting techniques.

• Use a strong hashing algorithm like SHA-256 or bcrypt to hash passwords.

• Add a unique salt to each password before hashing to prevent rainbow table attacks.

• Store the salt and hashed password separately in the database.

• Use a secure connection (HTTPS) when transmitting passwords.

• Implement password policies to enforce strong passwords and reg

To tune stored procedure performance with heavy database, optimize query execution plan, use indexes, and minimize data transfer.

• Optimize query execution plan

• Use indexes

• Minimize data transfer

• Consider partitioning large tables

• Use stored procedure parameters

• Avoid using cursors

• Use SET NOCOUNT ON

• Consider using temp tables

• Regularly update statistics

Oops (Object-Oriented Programming) is a common paradigm in real projects.

• Oops helps in creating modular and reusable code.

• It helps in reducing code duplication and increasing code maintainability.

• Common oops concepts include inheritance, polymorphism, and encapsulation.

• Examples of oops languages include Java, C++, and Python.

MVC provides better separation of concerns and modularity, making it easier to maintain and scale applications.

• MVC separates the application into Model, View, and Controller components

• This separation allows for easier testing and maintenance of each component

• MVC also allows for easier scalability and modularity of the application

• Non-MVC architectures can lead to tightly coupled code and difficulty in making changes
