• “Balancing communication across different time zones requires strategic planning and effective use of technology. I would propose setting up regular meetings at a mutually agreed-upon time that respects all parties’ working hours. For non-urgent matters, asynchronous communication tools like email or project management software can be utilized. This ensures everyone stays informed without disrupting their workflow. To avoid confusion, it’s crucial to always clarify the time zone when scheduling meetings. Lastly, being culturally aware and respectful of holidays or non-working days in other countries is essential for maintaining good relationships with global clients.”

6. Could you share an innovative solution you’ve developed for a complex technical problem?

• “In a past project, we faced performance issues due to high data volume. Traditional database queries were inefficient and time-consuming. I proposed using Elasticsearch, a search engine based on Lucene library, for faster data retrieval. It indexes data, making searches quicker than traditional databases. After implementing Elasticsearch, the system’s efficiency increased significantly, reducing query times from minutes to seconds. This solution not only solved our immediate problem but also provided scalability for future growth.”

7. How have you ensured code quality in your past projects, keeping in mind EPAM’s emphasis on high-quality deliverables?

• “To ensure code quality in past projects, I have adhered to best coding practices like DRY (Don’t Repeat Yourself) and KISS (Keep It Simple, Stupid). I’ve also used Test-Driven Development (TDD), which involves writing tests before the actual code. This approach helps catch bugs early and ensures that every piece of code has a purpose. Moreover, I regularly performed code reviews with my team. These sessions not only helped identify potential issues but also facilitated knowledge sharing about different parts of the system. For maintaining consistency across the project, I utilized linters and formatters. They enforce style guides automatically, reducing trivial errors and improving readability. In terms of tooling, I leveraged Continuous Integration/Continuous Deployment (CI/CD) pipelines for automated testing and deployment, catching any integration issues swiftly. These strategies align well with EPAM’s emphasis on high-quality deliverables, ensuring robust, maintainable software.”
