Example Table of Answers
| Quality | Description of Answer | Reasoning |
|---|---|---|
| Bad | "I worked with a team to launch an app. I was responsible for several tasks including some coding and meetings. The app works well and customers seem happy." | Lack of specificity and detail; no clear explanation of role, challenges faced, or measurable outcomes. |
| Good | "I was part of a team that launched a scheduling app, serving as the backend lead. I implemented a new caching solution to decrease load times by 30%, which significantly improved customer satisfaction scores. I coordinated with the front-end team to ensure seamless integration." | Better specificity with clear role and technical contributions. Mentions teamwork and a key outcome. However, it lacks details on problem-solving processes and stakeholder engagement. |
| Outstanding | "In my role as the engineering lead for Project X, I orchestrated the end-to-end development and launch of a real-time analytics platform that processed millions of transactions daily. I led a team of 10 engineers, fostering a collaborative environment to innovate our use of Big Data technologies. We encountered significant data integrity issues initially; I spearheaded a strategic pivot that enhanced our data processing pipeline, improving data accuracy by 40%. This directly contributed to a 50% increase in user retention. Post-launch, I conducted a series of knowledge-sharing sessions to elevate our department's technical acumen." | Highly detailed, showcasing leadership, technical expertise, effective problem-solving, significant impacts, and proactive learning. Clearly communicates the candidate's direct contributions, the challenges faced, and the strategic decisions made. |
STAR Answer: Bad Level
Situation: When I was working at my previous job, our team decided to create a new app because we wanted to try something different that could potentially attract new users.
Task: My job was to help out with the coding and participate in meetings where we discussed various features we thought would be cool to include in the app.
Action:
- General Participation: I did some of the coding, wrote a few tests, and reviewed code from other team members now and then. I also sat in on the planning meetings.
- Collaboration: Worked alongside the rest of the team in a supportive capacity, helping where I could with the app's development, but I didn't lead any part of the project myself.
Result:
- The app was eventually launched and was pretty well-received from what I remember. I think it got a decent number of downloads and people in the company seemed happy with our work.
This response is considered "Bad" because it fails to convey meaningful specifics about what the app was, the candidate's actual contributions, or the skills they applied. It lacks details on the technical challenges faced, how they were addressed, and the success metrics of the product launch. The actions described are passive and do not highlight the candidate's initiative or impact. Overall, this answer does not demonstrate the candidate's capabilities or provide convincing reasons why they would be a valuable addition to the team. The answer is too generic, suggesting a lack of preparation or inability to articulate one's experiences effectively, which are critical red flags in an interview setting.
STAR Answer: Good Level
Situation: Last year, my previous company, a mid-sized tech startup, decided to tap into the project management market by developing a new task management app. The goal was to create an app that not only addressed the basic needs of task management but also incorporated AI to predict task durations and recommend resource allocations.
Task: As a software engineer, I was tasked with leading the backend development team. My responsibilities included designing the database schema, implementing the server logic, and integrating AI features that our data science team developed.
Action:
- Technical Implementation: I started by designing a robust database schema that could handle large volumes of data efficiently. For the server logic, I implemented RESTful APIs using Python and Flask, which I chose for their simplicity and scalability.
- Team Coordination: I held bi-weekly meetings with the front-end team to ensure our work was closely aligned. This helped in smoothing out any potential integration issues early in the development process.
- AI Integration: The integration of AI features was challenging. The models our data scientists created were sophisticated, but deploying them into a production environment required significant adjustment. I collaborated closely with the data science team, setting up a middleware layer that could preprocess data to be fed into the AI models and handle the output predictions.
Result:
- Our app was launched on schedule and within the initial budget. It featured high performance and reliability, handling up to 10,000 users simultaneously at launch.
- Post-launch, we received positive feedback from users about the AI features, noting that the predictions were helpful and reasonably accurate.
- The app has maintained a 4-star rating on various software review platforms and has onboarded 3,000+ companies to date.

Conclusion
A well-rounded answer not only covers what was done but also how it was done and what the outcomes were, reflecting on the individual's role in the success. It should display a blend of technical and soft skills, showing the interviewer that the candidate is competent, has initiative, and can handle challenges effectively. These insights help in understanding the candidate's potential fit for the role in terms of both skills and cultural alignment.
