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.

96,330 software developer interview questions shared by candidates

As another person mentioned, they lack of structure in an interview. They just ask whatever question pops in their head at a given moment. Usually an interview starts with a presentation of a company the position the candidate applied, etc. On top of that the tech lead was basically trying to see if I lied in my resume and started ask questions as to trap me, guy thinks he's a private detective. He seems to have outdated knowledge on software architecture. They were about 15 minutes late, didn't even bother to apologize, they treated me as if I was a liar and they lacked organization during the first interview. If the interview process if bad itself, you can imagine the rest. Being a laid back company doesn't justify bad manners.

Write a real time Chat application - Secure registration / authentication (using Google or Facebook login, or similar) - CRUD chat rooms - Any user join/leave multiple chat rooms; persist preferences to a database - Store all messages sent/received in a database so that users get their history when they log back in, or can receive messages offline and see them when they log back in - Real time message delivery using WebSockets - Must support OVER 10,000 concurrent users, and you need to demonstrate that this works with some kind of load test (did they want me to pay money and spin up a cluster in Google cloud or something? Or did they just want me to increase the number of file handlers per process on my computer and somehow have it scale adequately on my dual core MacBook Air? Insanity.) - Licensing restrictions to MIT license???? Why would they care? Are they intending on using this code for their production systems after I give it to them? - Must be scalable, maintainable, testable If I were scoping this kind of program for a real job, the MVP would be several dev weeks of work, including the planning/design portion. I've never met a single dev that could bang out something like this in a day or two from scratch. It almost seemed like they want you to write a bunch of free code for them to use in one of their internal projects.
