Computer Vision Engineer Interview Questions
Sample answer to the question
I have experience in conducting feasibility studies for computer vision applications and evaluating their potential impact. In my previous role, I worked on a project where we were tasked with developing a computer vision system to detect defects in manufacturing processes. To conduct the feasibility study, I first researched existing computer vision algorithms and techniques that could be applied to our problem. I also evaluated various machine learning models and techniques to determine the best approach. I then conducted experiments to test the performance of different algorithms and models on our dataset. Based on the results, I assessed the feasibility of implementing a computer vision solution and estimated its potential impact on reducing defects and improving efficiency.
A more solid answer
In my previous role as a computer vision engineer, I had the opportunity to conduct multiple feasibility studies for computer vision applications and evaluate their potential impact. One project involved developing a computer vision system for object detection in autonomous vehicles. To conduct the feasibility study, I first analyzed the specific requirements and constraints of the application, such as real-time performance and accuracy. I then researched and experimented with various computer vision algorithms, such as Faster R-CNN and YOLO, to determine their suitability for the task. Additionally, I evaluated different machine learning models trained on large annotated datasets to assess their performance and generalization capabilities. By comparing the results, I could estimate the feasibility of developing a robust and accurate object detection system for autonomous vehicles. In terms of evaluating potential impact, I collaborated closely with the product management team to understand the desired outcomes and key performance indicators (KPIs). I defined metrics to measure the impact of the computer vision system, such as detection accuracy, false positive rate, and processing speed. I conducted extensive benchmarking tests to assess these metrics and quantitatively evaluate the potential benefits of implementing the system. The results showed significant improvements in object detection accuracy, reduced false positives, and faster processing times compared to existing solutions. This highlighted the positive impact the computer vision system could have on improving the safety and efficiency of autonomous vehicles.

An exceptional answer
Throughout my career as a computer vision engineer, I have gained extensive experience in conducting comprehensive feasibility studies for various computer vision applications and evaluating their potential impact. One notable project involved developing a computer vision system for real-time object tracking in a retail environment. To conduct the feasibility study, I first conducted a thorough analysis of the specific requirements and challenges of the application, such as occlusion, varying lighting conditions, and complex backgrounds. I researched and experimented with state-of-the-art computer vision algorithms, including DeepSORT and SORT, to identify the most suitable approach for real-time object tracking. I also evaluated different tracking metrics, such as intersection over union (IOU) and average precision, to assess the accuracy and robustness of the algorithms. Additionally, I performed extensive testing using a diverse dataset containing various object classes and scenarios. By analyzing the results and comparing them with manual annotations, I could determine the feasibility of developing a reliable and accurate object tracking system for the retail environment. In terms of evaluating potential impact, I collaborated closely with the business team to understand the specific goals and objectives. We defined key performance indicators (KPIs), such as customer conversion rates, time spent in-store, and overall customer satisfaction. I integrated the developed computer vision system into the existing retail infrastructure and conducted extensive A/B testing to evaluate the impact on the defined KPIs. The results showed a significant increase in customer engagement, a reduction in theft incidents, and improved operational efficiency. By analyzing the data and conducting statistical analysis, I quantified the positive impact of the computer vision system and presented the findings to the executive team, which led to the decision to deploy the system across multiple stores.
