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.

They asked me puzzles which i think is the most unexpected and toughest part for me.(But somehow i managed to answer the puzzles) THE PUZZLE IS->> Over at your local high school, the main hallway has a bank of 100 lockers. All of these lockers, labeled 1 through 100, start with their doors closed. The resident class clown decides to open every locker door. He then returns to the front of the row and toggles (opens/closes) every 2nd locker door (2,4,6,8...) in the hallway. That is, he goes to every 2nd locker, if it's open, he closes it, if it's closed, he opens it. The class clown repeats this for every 3rd locker (3,6,9...), then every 4th locker (4,8,12...), then every 5th (5,10,15...), etc. until he finally repeats for every 100th locker. After the class clown is done, which locker numbers will end up closed, which will end up open?
