Surbhi G. - "When choosing a machine learning algorithm for a system, I take several parameters into account. Initially, I identify the problem's nature, whether it's categorization, regression, clustering, or dimensionality reduction. For instance, if I'm dealing with a classification problem, I might lean towards algorithms like Decision Trees, Logistic Regression, or SVMs. Moreover, the availability of resources, including memory and computation power, is important. For large datasets, I might prefer an a"See full answer

Praful B. - " The productofarrays() function works by first creating an empty array to store the product of the two integers. Then, it iterates through the first array and multiplies each element by each element in the second array. The product of each element is then appended to the product array. Finally, the product array is returned def productofarrays(array1, array2): """ Calculates the product of two integers represented by two arrays. Args: array1: The first array. array2: The se"See full answer

Surbhi G. - "Ensure immediate safety: The first priority is to secure the vehicle and its occupants by stopping the engine, activating hazard lights, and unlocking doors. Assess the situation: The car evaluates the extent of damage, determines its location, and checks on the status of passengers.

Shivam S. - "Binary search is the technique to search an element in a sorted array in O(log(N)) time. It is also used in problems wherever we find monotonically increasing or decreasing patterns."See full answer

Exponent - "This is a Technical question. It tests your ability to understand high level technical concepts. Even though your job won't have any coding involved, you'll still need to understand these concepts. Being able to cover all these topics with clarity communicates confidence in your interviewer. Unfortunately, there's no formula for technical questions, but some general tips are: Use analogies when you can Break your solution into clear, bite-size steps Don't be afraid to use examples to b"See full answer

Vamsi K. - "How would you place Amazon Alex hardware in a car, if car software integration was not an option? Let me understand the context and the situation Is Amazon really trying to experiment if they could be a new device category in the cars (or) Is it that they did not get the right partnerships that led to this decision (assuming this is the case) What could be the objectives why Amazon will get interested in this? Apple and Google are getting entrenched in this space and Amazon has almost n"See full answer
