The most comprehensive bank Interview Answer Review tooling available online.

With a major product launch on the horizon, expecting to triple the user load. The infrastructure was non-optimized for demand and incident response was non-harmonious across teams with no set process.

As the SRE Manager, I'd have to implement project changes to infrastructure to accommodate high availability and scalability. I discovered a long-standing issue surrounding incident response and observability that would make it all the more difficult to achieve reliability under pressure and peak traffic.

Therefore, instead of fulfilling the project requirements as presented, I became an advocate for change across the organization. I established an observability platform with 100% stack coverage, created custom SLOs/SLIs/error budgets to enhance performance and reliability visibility, drafted and socialized an incident management playbook across the company and held hands-on trainings for all respective teams. In addition, I advocated for Terraform for Infrastructure as Code to help with deployment time and held FinOps reviews to help eliminate redundant costs in cloud spend.

As a result, we did not only survive the 3X traffic upon product launch with zero critical incidents, but we also achieved 15% saves the following years in cloud costs and 40% faster deployments. Many of the processes I created were adopted as company-wide best practices.

Having a long-term goal clearly set, breaking it down into near-term goals helps visualize our progress and what is expected on a day-to-day basis. By hitting the near-term goals I'll understand and grasp the depth, gain insights from the stakeholders, and would be able to achieve the long-term goal. setting near-term goals also help analyze trade-offs along the way

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。

The last conference I attended was the Open Source Security Foundation. As I was leading the Dart & Flutter security program I wanted to learn about the innovations, tooling and services that other open source projects were using.

There were interesting conferences for tooling to sign artifacts with a single command and how the open source community was working in tooling to build, sign and release artifacts in a secure way for everyone using GitHub.

I learned that there were many technical innovations that I could use to speed up the Flutter Security Program, for example implementing secure build workflows using github actions. I also met several people working on similar projects and took the opportunity to share our lessons learned and challenges. Later on the connections with the open source security foundation proved very useful during technical reviews and collaborations.

I was working on a high stake project with very high visibility from my senior management.

Me and my manager were thinking of can we leverage the quality of the development using help from QA team. He wanted to keep the QA team separate. His point of view was that a separate team would keep clear focus for the team and they would focus on finding more customer facing bugs. I thought that we should have QA embedded in the scrum team as that would help in easier collaboration and quicker bug fixes plus this is a more efficient way. Though I understood his point of view I always believed that in QA embedded inside the scrum team. I went back had a thought to measure the merits and demerits of the proposals. I put down in a slide the merits and demerits of each. Merit from having a separate team, clear focus and better filtering of quality, demerits less collaboration with development team. I then proposed that the QA engineers attend the calls of dev teams but keep a separate QA board for their tasks. This will give clarity of what bugs they find, what test scenarios they create and finally the metrics to measure the bugs reported per development. My boss and I both agreed as it solved the problems of each proposals

So for my current role we move in a very fast paced environment, and we brainstorm new ideas everyday on how to make our workflow more efficient and more reliable, which can definitely get overwhelming over time. So I would first assess projects' urgency and impact, and then for each project, I break it down into small milestones. After that I track them on project management tools like Jira to ensure I allocate my time effectively and communicate proactively with stakeholders

I am pretty passionate about Reddit. In a world where media is biased and polarized, Reddit threads gives me a sense of how local communities view the world. It helps me get grounded in reality of what different cadres of people are thinking by browsing different communities. Reddit is very engaging, as in, you can comment and instantly receive feedback. While there is a lot of "internet hate" and "misinformation" in Reddit communities and threads as well, looking at a wider spectrum of communities within Reddit, especially the differing ones, helps you form a less polarized and biased opinion. I prefer contributing by asking open-ended questions and if I have an opinion, posting it respectfully as a question. I also respond to scientific minded questions that I have qualifications to answer. By selectively responding and answering questions with some due diligence, I keep the communities I am a part of thriving and truth-based.

while reviewing one of the older projects that was currently implemented in the company I noticed that there was no alerting in place if the data pipeline breaks, the data pipeline has never been broken and it never failed for the last 2 years. it was a pipeline where the data would be dropped into an sftp bucket by the customer every hour and then it was moved to an s3 bucket where s3 triggers were implemented to moved the data in to queue. So in case there is an issue with the data not being processed we would only know when the we see a drop in volume. I identified it as a potential issue with the system and worked on a proposal to have monitoring in place so we are notified when there is an error. I worked with the program manager and devised a plan on how to implement the alerting and the time lines as well as the effort that will be needed to implement it. I mapped the impact of not having it to the current goals of the company and then put forward a proposal of implementing the alerts to the business and took their buyins. after getting the buyins I proposed the task to my team and some of the sr devlopers were not too keen on implenting the alerts, I gave the task to some of the Jr devlopers and the alerts were implemented. after the implementation we discovered that for some hrs in a day we werent getting any files so instead of getting 24 files in a day we were getting 20 files a day in an average. This was rectified by talking to the customer and the missing data was solved. but this made the whole team realize the importance of monitoring and alerting. It also bosted the moral of the Jr developers seeing the direct impact they made to the business goals

i was head of events in a student activity called aces and it was a magnificent experience as i gathered a team wich i chose by myself and my partner as they all were hardworkers and creative thinkers of course we had some trouble with them as some of them were being lazy about doing there tasks or procranstinating but we were able to motivate them each time so they would give their best
