Software Developer Interview Questions

Software development is an in-demand career path, and it's also a job that can provide opportunities for high earnings and professional fulfillment. When interviewing for software developer positions, you'll likely face questions about your hard and soft skills and how you manage projects efficiently.

Top Software Developer Interview Questions & How to Answer

Question 1

Question #1: What type of software development do you currently do?

How to answer
How to answer: When answering a question about your current software development projects, emphasize the coding languages and technology stack that you use. This question helps an interviewer determine if you have the skills needed to handle the workload.
Question 2

Question #2: Describe a development issue you faced and how you solved it.

How to answer
How to answer: Talking about a specific situation allows you to describe your problem-solving methods and the actions you took to resolve the problem. Use the STAR method (situation, task, action, result) to provide a clear picture of the problem you faced in development and what you did to fix it.
Question 3

Question #3: How do you handle the QA process?

How to answer
How to answer: Quality assurance is an important aspect of software development, and the process may fall on the developers in a smaller organization that doesn't have a designated QA team. If you face a question about the QA process, the interviewer may be trying to determine whether you would be willing and able to take on testing and bug fixing as part of the role.

After his one hundredth pass in the hallway, in which he toggles only locker number one hundred, how many lockers are open?

Write a program that given a 2D integer matrix (default value: 0) and a coordinate in the matrix, it sets all of the elements diagonal to the coordinate to a value of 1 (so that if you wrote it on a piece of paper there's an X with the coordinate at the center).

#1: We have a linked list, but it is special in that it can have pointers down, as well as next. Any node can have an arbitrary number of links down as well as across. Write a function that will "flatten" this linked list so that it does not have any down pointers, but all elements remain in order.
