Microsoft Research Consultant Interview Questions, Process, and Tips

Web API verbs include GET, POST, PUT, PATCH, and DELETE for different operations on resources.

• GET is used to retrieve data from a server

• POST is used to create new data on a server

• PUT is used to update or replace existing data on a server

• PATCH is used to partially update existing data on a server

• DELETE is used to remove data from a server

Azure Key Vault is a cloud service for securely storing and managing sensitive information such as keys, passwords, certificates, etc.

SQL data types differ in storage size, range of values, and operations that can be performed on them.

• Different data types have different storage sizes, such as INT vs VARCHAR.

• Data types have different ranges of values they can hold, like DATE vs TIMESTAMP.

• Operations that can be performed on data types vary, for example, arithmetic operations on numeric types but not on text types.

Factory design pattern is used to create objects without specifying the exact class of object that will be created.

• Factory method pattern defines an interface for creating objects, but lets subclasses decide which class to instantiate.

• Example: Java's Calendar.getInstance() method returns a Calendar object based on the current time zone and locale.

• Factory pattern promotes loose coupling by eliminating the need to bind a

SOLID principles are a set of five design principles in object-oriented programming.

• Single Responsibility Principle: A class should have only one reason to change.

• Open/Closed Principle: Classes should be open for extension but closed for modification.

• Liskov Substitution Principle: Objects of a superclass should be replaceable with objects of its subclasses without affecting the program's correctness.

• Interface Segregati...read more

Asynchronous programming allows tasks to run independently, while multithreading involves multiple threads executing tasks simultaneously.

• Asynchronous programming is useful for I/O-bound operations, such as network requests or file operations.

• Multithreading is beneficial for CPU-bound tasks that can be parallelized, like complex calculations.

• Asynchronous programming can improve responsiveness in applications by allowin...read more

Handle exceptions in asynchronous programming by using try-catch blocks and error handling functions.

• Use try-catch blocks to catch exceptions in asynchronous code

• Use error handling functions like .catch() or .then().catch() in Promises

• Consider using async/await for cleaner error handling syntax

• Use libraries like async/await or Bluebird for advanced error handling features
