At my previous role, I was leading a fraud detection AI model deployment for a financial services client. The model aimed to reduce fraudulent transactions by 25% while maintaining a low false positive rate.

I was confident in the model’s performance in the test environment, but when we deployed it in production, we noticed an unexpected spike in false positives. Transactions flagged as fraudulent were legitimate, causing disruptions for customers and increasing manual review work. To resolve this, I:

1. Investigated the issue by comparing training and production data.

2. Identified data drift—the model was trained on historical data, but recent transaction patterns had changed.

3. Worked with data engineers to implement real-time data monitoring.

4. Retrained the model with up-to-date data and adjusted hyperparameters to improve generalization.

This fix reduced false positives by 25%, improved fraud detection accuracy, and ultimately saved $500M in operational savings across multiple initiatives. This experience taught me the importance of continuous model monitoring and proactively accounting for data drift. Now, I always incorporate data validation pipelines and feedback loops into AI deployments to prevent similar issues.

As a QA leader I had to choose between run a full check of a new functionality that wasnt very popular or use or let the change pass over with the aprove of the PM for some time saving. I choose run the full check, take a few days more, but when the functionality goes to production it works well, without any bugs.

S（Situation）：在2024年9月底，我所在团队灰度上线了一个重要新功能。上线不久后，我们注意到产品的 NPS 分数出现了明显下滑。我的老板非常担心这个变化是由我们新功能引起的，因此建议我们暂停功能的进一步上线。

T（Task）：考虑到我们灰度期间已经收到不少正向的用户反馈和行为数据，我担心贸然暂停功能会影响节奏，并可能误判问题根源。我希望找出 NPS 下滑的真正原因，并用更稳妥的方式推进问题解决。

A（Action）：我首先分析了 NPS 下滑的时间节点，发现其发生在我们功能上线之前。结合用户评价存在滞后性的特点，我判断两者未必直接相关。随后我深入分析了近期的低分评价和客服 ticket，发现主要问题集中在打印出错、页面崩溃等历史遗留的功能性 bug。
我将这些发现整理成文档分享给老板，建议我们先优先修复这些问题，并继续观察 NPS 变化。同时，我也请他指出是否存在新功能相关的反馈痛点，以便一并跟进优化。我们快速完成了 hotfix，并验证后上线。

R（Result）：两周内，NPS 分数从 xx 回升到 xx（如能填具体更好），我们功能也顺利推进至全量发布，后续使用量增长了 xx%。老板也认可了我们以数据驱动决策的方式，对我在这件事中的判断力和推进力给予了肯定。

I was working on the large scale entrprise wide program that included multiple teams and stakeholders .During the initial phase of the program on discussion with Business stakeholders , Product Management team , PO , Tech SME to determine the scope of program , prioritization & aligning on the business objectives  and tech objectives there was multiple discussion and it was tough to get the agreement due to multiple people having conflicting agenda and need .  I received the feedback that there was lot of time being wasted and people are not aligning on the subject . This led me to reflect back and breakdown the work and structure of how we were approaching  the topics to be discussed & limiting to the required audience and building a steering committee that will be a small set of devision makers representing from business stakeholders , Product management , Technology team additional I also prepped the teams offline on the discussion topics and things they need to come prepared so that our meeting agenda is clear an we can effectively discuss and prioritize on the scope due to the initial prep work done offline . This helped me in always being open for feedback and being adaptive to the ongoing situation and doing initial ground work so that there is clear and effective communication transparency

Situation:

I was laid off from my first job just four months after joining due to budget constraints. This was a major setback for me as I had just started my career. Around the same time, my father suffered a heart attack, which required me to stay at home and take care of him while he was on bed rest for several months. The combination of losing my job and dealing with a family emergency left me feeling devastated, and I struggled to apply for new roles.

Action:

Despite these challenges, I remained determined to grow in my career. While caring for my father, I focused on upskilling myself:

• I attended mentor sessions on ADPList to gain industry insights.

• I reached out to experienced designers on LinkedIn for portfolio reviews and feedback.

• I enrolled in courses through Interaction Design Foundation (IxDF) to expand my knowledge.

• I continuously improved my portfolio and resume, incorporating the feedback I received.

I also actively networked with professionals, which helped me regain confidence and visibility in the industry.

Result:

My persistence paid off. Where I once struggled to pass resume screenings, I started receiving recruiter calls consistently. In fact, this very interview happened because I proactively connected with a senior designer, shared my portfolio, and received a referral for this role. This experience not only strengthened my portfolio and skills but also taught me the power of perseverance, networking, and continuous learning.
