My approach to writing unit tests involves identifying key functional components of the code, and then developing tests that validate each component's expected behavior. I also make use of test automation tools to streamline this process, and conduct regular code reviews and debugging sessions to ensure that the tests are comprehensive and accurate. In terms of code coverage, I aim to achieve 90% or greater, though this can vary depending on project requirements and constraints.4. When developing applications that involve sensitive data, I follow several key security practices, including encrypting data both in transit and at rest, implementing multi-factor authentication, and regularly conducting security audits and reviews. I also make use of security frameworks such as OWASP to ensure that my code is free of common vulnerabilities and exploits.5. When optimizing application performance, I typically start by using profiling and bottleneck analysis tools to identify areas of the code that are causing performance issues. I then work to optimize these areas by optimizing algorithms, reducing I/O and network traffic, and making use of caching and other optimization techniques. I also conduct regular load testing and benchmarking to ensure that my changes are having the desired effect.Round 3:1. Salesforce is a cloud-based CRM platform that provides a wide range of tools and services for application development and deployment. Its cloud architecture is designed to be highly scalable, flexible, and secure, with features such as multi-tenant architecture, automatic upgrades, and data replication for disaster recovery. As a developer, I would leverage these features to build robust, high-performance applications that are capable of serving a large number of users, and that can be easily scaled up or down as needed.2. When designing databases for large-scale applications, I pay close attention to database structure and normalization to ensure that the data is well-organized and easily accessible. I also make use of indexing and caching technologies to improve query performance and optimize database performance. Additionally, I conduct regular database maintenance and backup tasks, and make use of database monitoring and logging tools to ensure that the database is running smoothly and securely.3.STAR Answer: Situation: In a previous project, I was tasked with adding a new feature to an existing application that had already undergone several iterations and revisions.Task: The feature was relatively complex, and there were competing demands from various stakeholders in terms of functionality and scope.Action: To balance these competing demands, I first conducted a thorough analysis of the feature requirements and worked closely with key stakeholders to identify their needs and priorities. I then proposed several potential solutions that would balance technical feasibility with usability and business goals, and worked collaboratively with the team to iterate on these solutions until we arrived at a suitable solution.Result: The end result was a feature that met the needs of all stakeholders while also being technically feasible and reliable. Furthermore, the collaborative approach we took helped to foster greater buy-in and engagement from the team, and ensured that the feature was successful in meeting its objectives.4.
