2. Review and example answer

Now you can try answering the above questions, and let the AI coach review your answers and provide example responses.

Prompt

Context:
Here is a software engineer interview question:

"Can you describe a time when you successfully optimized a software process or functionality? Specifically, how did you manage to achieve a 30% decrease in data processing time in one of your projects?"

Here is my answer:

"No problem. During my internship at this company, I used Grafana and Datadog to analyze API response time bottlenecks. I discovered that the code was redundantly querying some database tables in the API. By modifying the code, I reduced the database query time. Additionally, I analyzed the efficiency of the database queries and found that creating composite indexes could speed up the queries. After discussing the solution with my manager, we established composite indexes on two tables, which ultimately decrease the API response time by 30%."
Requirements:

Target company is Google LLC
Review my answer, tell me where I can improve based on these five points:

Specificity: Does the answer provide specific examples from the candidate’s past experiences? Specific details help illustrate the candidate's skills and how they handle situations relevant to the position.
Relevance: Is the example or story shared relevant to the question asked? The response should directly address the question and show how the candidate's experience is applicable to the job they are applying for.
Structure: Does the answer follow a clear and logical structure? Common frameworks like STAR (Situation, Task, Action, Result) or CAR (Context, Action, Result) help in organizing the response clearly and concisely.
Clarity: Is the answer clear and easy to understand? It should be articulated well without unnecessary jargon or overly complex descriptions.
Outcome: Does the candidate clearly describe the outcome or result of their actions? It’s important that they highlight the impact of their decisions and actions, showing their contribution to a positive outcome.


Your example answer should use STAR method based on my experience, action and result should be detailed
action and result in STAR should use bullet points and every bullet points should start with keywords.

Response From AI Coach

Your answer provides a good foundation for illustrating your ability to optimize software functionality, but let us improve it based on the five key points:

Specificity: Your answer mentions using Grafana and Datadog, and creating composite indexes, which are great specific details. However, it could further benefit from mentioning specifically what the queries were before and how they were optimized (if possible without disclosing sensitive information).
Relevance: You directly address the decrease in data processing time, which is relevant to the question asked. Ensuring you keep the focus on this specific optimization throughout the response will maintain its relevance.
Structure: Your answer can be rearranged to follow the STAR (Situation, Task, Action, Result) structure more clearly. This will help in organizing the information in a clearer, more logical format.
Clarity: The response is relatively clear but using technical terms like "composite indexes" could be briefly explained to make sure all interviewers (who might not all be technical) can understand.
Outcome: You mention the decreased API response time by 30%, which is great. Expanding slightly on how this improvement impacted the end-user or the business would make this even stronger.
Example Answer Using STAR Method

Situation:
During my internship at XYZ Inc., I was responsible for optimizing RESTful services developed in Java using the Spring Framework. Our team noticed that certain services were experiencing slow response times, impacting overall application performance.
Task:
My task was to identify the causes of these delays and implement solutions to improve data processing times.
Action:
Here’s how I approached the issue:

Analysis with Tools: I utilized Grafana and Datadog to monitor and analyze API response times, which helped identify bottlenecks.
Code Evaluation: On reviewing the code, I noticed redundant queries to the database. I optimized these queries to reduce unnecessary data processing.
Database Optimization: Further analysis revealed that the execution of database queries could be enhanced by introducing composite indexes. After consulting with my team lead, we decided to apply composite indexes on two critical tables.
Collaboration and Testing: I worked closely with the database management team to implement these changes and conducted thorough testing to ensure these modifications did not disrupt existing functionalities.

Result:
These optimizations led to a significant improvement in performance, reducing the data processing time by 30%. This enhancement not only accelerated the response time of our services but also improved the overall user experience, leading to less reported issues and higher satisfaction ratings from the end-users.

This response clearly lays out the situation at hand, what task you were charged with, the specific actions you took to address the issue, and the beneficial results of those actions, all while keeping the discourse clear and easy to follow.
