Infocusp Interview Questions, Process, and Tips

Q1. Why did you choose Yolo over two-stage detectors?
Ans. 
Chose Yolo for its real-time processing speed and simplicity compared to two-stage detectors.
• Yolo is faster than two-stage detectors as it processes the image in a single pass

• Yolo is simpler to implement and train compared to two-stage detectors like Faster R-CNN

• Yolo is more suitable for real-time applications where speed is crucial, such as autonomous driving or video surveillance

Q3. Implement IOU function
Ans. 
Implement IOU function for evaluating object detection models.
• Calculate the area of overlap between two bounding boxes.

• Calculate the area of union between two bounding boxes.

• Divide the area of overlap by the area of union to get IOU.

• IOU = Area of Overlap / Area of Union

• Example: Bounding Box 1 (x1, y1, x2, y2) = (0, 0, 4, 4), Bounding Box 2 (x1, y1, x2, y2) = (2, 2, 6, 6)

Q4. Implement Dataset for object detection
Ans. 
Implementing a dataset for object detection involves collecting and labeling images with bounding boxes around objects of interest.
• Collect a diverse set of images containing the objects you want to detect

• Label the objects in the images with bounding boxes to indicate their location

• Split the dataset into training, validation, and test sets for model evaluation

• Augment the dataset by applying transformations like rotation...read more

The entire process began with an aptitude and programming assessment, followed by a call from the recruiter to schedule the first technical interview 15 days after the assessment. During the interview, the interviewer primarily asked basic questions related to my resume, focusing on the MERN stack and essential concepts such as the event loop in JavaScript, the box model in CSS, and hooks in React. However, I was not shortlisted for the second round of interviews.

Q1. Could you elaborate on the experiences you have detailed in your resume, such as the basic questions related to the MERN stack that you were asked?

Q2. What is an anchor tag in HTML, what is the event loop in JavaScript, what is the box model in CSS, what are padding and margin, what are hooks in React.js, what is CORS in Node.js, and what is a JWT token?
Ans. 
Anchors in HTML, event loop in JavaScript, box model in CSS, padding and margin, hooks in React.js, CORS in Node.js, JWT token.
• Anchor tag in HTML is used to create hyperlinks. Example: <a href='https://www.example.com'>Click here</a>

• Event loop in JavaScript is responsible for handling asynchronous operations. Example: setTimeout() function

• Box model in CSS defines the layout of elements. It consists of conte...read more
