Tell me about a time when you failed badly and what you learned from it?

In my early days as Program Manager, I managed a project for one of our main customers. This project consisted in a touch screen device to control a Large format printer for HP. The project had a very tight schedule and I promised to deliver the first EVT units in a certain date.

T: As PM, it was my responsibility to coordinate a cross-functional team to deliver the program on time, within budget, and in line with the scope agreed with our customer.

A: When I started to dive deep into the project and analyze the technical details, I realized that meeting the original delivery timeline was not feasible. So, I immediately met the core team to develop a new and realistic schedule to mitigate the issue. To ensure better alignment, I implemented daily opening and closing meetings with the team to monitor activities and prevent task duplication between cross-functional teams. Two key factors contributed to the milestone delay: a delay in component deliveries and one mistake on my part—I didn’t include in my schedule the LT for one of the Reliability tests required by Engineering before the Ok2ship milestone.

R: I highlighted the issue to my manager and shared with him the root cause of the problem and the new plan. Then, we reached the customer together to explain the situation and kept working together on the new committed schedule.

This experience taught me valuable lessons. Now, I always build buffer time into my project schedules and work more closely with core team members to anticipate potential risks. However, the most important lesson I learned was the value of honesty and proactive communication—raising concerns early is crucial to success.

I have been working as a data engineer for a combined total of three years, working closely with business leaders and engineers at different enterprises. where my main focus and speciality was in building reliable data pipelines that supports business decision making. I also have experience running a solo consultancy firm, where I have had the opportunity to consult and build end to end data products for businesses, which has allowed to be explore and hone my leadership, and communication skills on top of my technical expertise. Above all. in addition to the skills  I have learnt over the last three years, my experience in academia, especially as a consequence of my PhD research, I have a strong preference and a proven track record  in delivering complex analytical tasks.  All of the above essentially package me up as  an ideal candidate for this role.

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.

This is a product which we release recently it would check the recent breaches that happened exploiting certain vulnarability in the recent past and also check the vulnarabilties in the infrastructure and then provide a score based on severity. the higher the severity the higher the chance of getting breached. This was a great hit but two of our customers came back with a specialised request, the wanted to quantify the severity in terms of revenue loss so it would help them prioratize fixes on the infrastructure. This not only required heavy research but also defining the scope as well that where it fits in. The reason it was important to think about this feature because it was a big contract and our company wanted close it before the end of Q2. I had a planning sessions with the stake holders and product team, we defined the scope of the feature and then communicated with the customer and got all the buy ins, there had to be some repriorization required to imediatle start working on the project, I had a chat with my team and transperantly explained why this was such a high priority for the company and how it aligns with the company goals. This gave boosted their morale and also they saw the advantages of adding this feature and the moral was high.

In my last role I had to make a UX decision about the product that will balance functionality for the user without compromising performance. After testing a few options and validating it with internal stakeholders I released the updated UX, but then the CEO (who was a heavy user of the product) was against that change. I saw down with him and explained my reasoning and the process that I took to validate the solution, and gave him the option to try it himself on an early version. Once he saw the big picture he agreed that my solution was the right approach, but asked that next time I will consult with him before releasing changes like this.

I graduated in May 2024 and recently wrapped up my role at Bright Mind Enrichment. It was a great experience, and I stayed through my agreed-upon commitment.  At this point, I’m looking for a full-time opportunity that offers deeper ownership, long-term growth, and technical mentorship—especially in a full-stack environment like Atlassian’s.

During my early days at Teradata in 2015, I received critical feedback from my manager and colleagues that, although I had strong technical skills, I wasn't very vocal in expressing my opinions during discussions. I initially found this feedback difficult to accept because I believed that my work alone should be enough to communicate my value.  The task was to enhance my communication skills, particularly during team discussions and design reviews, to ensure that my thoughts and ideas were being heard and valued, rather than relying solely on the quality of my technical work.  Taking the feedback to heart, I made a concerted effort to prepare thoroughly for design discussions and technical meetings. I started to actively participate by sharing my opinions on the designs, asking questions to gain clarity, and offering my technical insights. Additionally, I sought feedback from my colleagues to better understand how I could communicate more effectively in these settings.  By consistently engaging in discussions, I found that my opinions were appreciated and valued, which led to more productive conversations and collaborations. This not only helped me build stronger relationships with my teammates but also improved my overall presence in the team. Over time, I became more confident in expressing my ideas and saw growth in my ability to communicate complex technical concepts more clearly and effectively.
