For a question like this, I had to convert it into a data structure in code, and then write a function to calculate the fill-up time. The questions were niche, and I had to write and run code within 50 minutes.įor instance, one question involved a rooftop with a unique shape, and I needed to estimate how long it would take to fill it with water, considering its various dips, like hills and valleys. The significant difference between the genuine military protractors and the civilian copies is labeling. I had two rounds of technical phone screens and an on-site interview, where they asked notoriously hard algorithm questions. Also, you can find military protractors sometimes being sold in military surplus stores. I give a 10/10 rating for the overall interview process, though, because I felt the interviewers at Stripe asked all the right questions, and the interview itself was most similar to what a real-life coding experience would be like as a software engineer. I remember there was a question about using a simplified version of Stripe's API to create a model for detecting fraud in orders and payments. They are trained rigorously to remove any biases from the hiring process and ensure new hires surpass the standard set by other peers in similar roles.īesides that, interviews at Stripe are much more of a real-world scenario, which makes it harder, too. The session brought a different team from the company into the hiring process. One interesting thing was that Uber had a session with "Bar Raiser" interviewers. Overall, it was a pretty intense interview experience. There was a psychological dynamic going into it - if I picked up on any signal on how I was doing, no matter how small, I gained some momentum to tackle the rest of the interview. During part three, when I was halfway done, they announced that the time was up. After completing the first part, we quickly moved to part two. The tricky part of the interview was that so many tasks were squeezed in at once, so I didn't have time to receive potential feedback - I wasn't able to know whether I did well or not. I remember asking the recruiter why the interviews were lighter than other companies, and they explained that reducing the number of rounds didn't impact the quality of hires but made the process less tiring for candidates they could also spend fewer company resources on interviews. Finally, use the bottom edge of the protractor as a straight edge to draw a line between the two points.Account icon An icon in the shape of a person's head and shoulders. Rotate the protractor and line the bottom edge up between the vertex and the small dot. Now, find the hash mark on the protractor that corresponds with the angle you want to draw, and draw a small dot outside of it. Then, line the bottom edge of the protractor up with the vertex and draw a straight line along it. Draw a small dot in the hole on the protractor to mark the vertex. To draw an angle with a protractor, first place the center point along the bottom edge of the protractor where you want the vertex of the angle to be. If the angle is facing left, use the top row of numbers. If the angle is facing to the right, use the bottom row of numbers on the protractor. Follow the other leg of the angle up to the protractor’s arc to see what number it intersects with and find the degree of the angle. Line up the bottom edge of the protractor with one leg of the angle. To measure angles with a protractor, first place the center point along the bottom edge of the protractor over the vertex of the angle you're measuring. You can use a protractor to measure and draw angles. The 2 measurement scales on the protractor makes this tool handy for measuring angles that open up from either direction.If your ray falls in between 2 whole numbers, like 50° and 60°, just count the lines to find your angle’s exact measurement. Protractors typically label measurements in 10s, but between each number are little lines that represent 1°.Or, line the edge of a piece of paper along the line. If the line doesn’t extend past the protractor’s arc, lengthen it with a ruler.If this angle opened from the left, you’d use the outer scale.We know to use the scale on the inside because the measurements are increasing as you move towards the line and they’re less than 90°. In the above image, the angle opens up to the right and is acute.The number that the ray passes through is your angle’s measurement in degrees. If your angle is obtuse, use the scale with measurements greater than 90°. If it’s an acute angle, make sure you’re looking at the measurements that are less than 90°. Use the scale measurements that are increasing in the direction that your angle is opening up in. Follow the other ray up to the measurements on the protractor's arc.
