Example of an expected response: “In my last project, I developed an e-commerce application using a microservices architecture. with RESTful APIs. I worked mainly with Express.js for the backend, implementing JWT authentication and Redis cache management to optimise performance. A major challenge was error handling during multiple API calls. I solved this problem by setting up a retry pattern and implementing exhaustive documentation using Swagger. This experience taught me the importance of a robust and well-documented API architecture.”
How do you prioritise your tasks under tight deadlines?
Effective management of time and priorities reflects the candidate’s professional maturity. A clear methodology for evaluating tasks is essential to maintain productivity under pressure.
The use of time management tools demonstrates the candidate’s ability to organise. Their mastery of agile methodologies and productivity tools reveals its professionalism.

Proactive communication with the team is crucial in times of stress. The candidate must demonstrate the ability to maintain full transparency on the progress of tasks.
Example of an expected response: “Faced with tight deadlines, I use an Eisenhower matrix combined with the Kanban method. to visualise and prioritise my tasks. For example, when launching a critical new feature, I first identify the components that are essential to the MVP. I use Trello to organise my tasks into ‘Urgent/Important’, ‘Important/Non-urgent’, etc. columns. I also use the Pomodoro technique to maintain my concentration. When I sense a potential delay, I immediately inform my project manager, proposing alternative solutions or readjusting the scope. This approach has enabled me to deliver 90% of my projects on time.
Assessing behavioural and interpersonal skills
As well as technical skills, soft skills are crucial to a web developer’s success as part of a team. These questions will help you assess the candidate’s interpersonal and behavioural skills.
How do you deal with negative feedback on your work?
“Recently, I’ve received some constructive criticism on the architecture of an application I had developed. My lead developer pointed out that my solution, although functional, was not sufficiently scalable for the future needs of the project. At the time, I took the time to listen carefully to his arguments and take note of his suggestions. Rather than getting bent out of shape, I saw this as an opportunity for improvement.
I’ve scheduled a peer programming session with him to understand his vision and identify areas for improvement. I then reworked the architecture by implementing the Repository pattern and adding an extra layer of abstraction. This experience taught me the importance of thinking in the long term and remaining humble in the face of feedback from my more experienced colleagues. Since then, I’ve included a systematic architecture review phase in all my major projects.”
This question assesses the candidate ‘s ability to receive constructive criticism and their emotionalmaturity. and its commitment to continuous learning. It also measures their level of humility and their ability to turn negative feedback into opportunities for improvement.
Describe a situation where you worked with other technical teams

As front-end developer, I took the initiative of organising weekly synchronisation meetings via Teams. I set up a dedicated Slack channel to facilitate real-time communication and used Confluence to keep shared documentation up to date. A major challenge arose when we discovered incompatibilities between the data formats expected by each team.
I suggested we organise a technical workshop to align our specifications and create a common APIcontract.. This proactive approach enabled us to resolve bottlenecks quickly. We ended up delivering the project two weeks ahead of schedule, and the experience has set a new standard for cross-team collaboration in the company.”
