A: “I assess technical debt by its impact on productivity and system risk. For crucial projects, I advocate for allocating sprints to address significant debts while balancing new feature development.”
17. With What Methodology Have You Worked With?
This depends on whether your company follows a determined project methodology. Many modern companies choose the Agile Methodology mainly because of its efficiency in managing workloads, due dates, design steps, and debugging processes, among other phases of a project. If your company works with the Scrum methodology, on interviews, you should make sure software engineering candidates know what Scrum or Agile is.
18. Are you comfortable working in a fast-paced, changing environment?
This question helps to identify if the candidate has worked in environments that evolve dynamically. And if they accommodate and enjoy that experience. Many software engineers are used to a predictable environment that is typical of big companies. And they rely heavily on having a team where the responsibilities are limited for each member. This question is ideal when you need a tech lead or when hiring for a small/ medium/ startup company.
19. How do you feel about code reviews?
In the software development process, code reviews are a must. This type of question lets you get a hint on how a developer might take feedback and how he is willing to help other team members. Also, to know more about the candidate’s knowledge and experience. And if they use testing methodologies, frameworks, or tools.
20. How do you maintain a work/life balance?
This question might be a small trick to see how a candidate prioritizes. You are not trying to find out how they handle their work and life daily. What you want to know is what’s important to them and how they act on that. A candidate who finishes tasks on time and overall works hard but also makes time for themselves, their hobbies, family, and friends is someone who understands the importance of work/life balance and how to take advantage of time.
