- By plotting it first but more accurate way is to use Dickey Fuller test to confirm it How do I choose which 10 new hotels to onboard on? - I said that we can look at the number of bookings, location, accessibility( metro, bus), is it near a tourist spot, reviews, stars. What if my model has recommended that all the 10 new hotels that we should onboard should be from the same area X? How do I add a constraint to fix this? - I don't even know what topic this question is from but I said maybe you can modify the cost function by adding a variable which will penalize the cost function based on the number of hotels it suggests that belong to the same area or maybe we can add constraints to the cost function If I add constraints to the cost function then it becomes a non linear optimization problem so how would you use linear programming to solve it? - I had no idea lol What is the difference b/w segmentation and clustering? - I answered that segmentation is a use case of clustering but apparently the interviewer said that clustering is an unsupervised learning algorithm while segmentation is a supervised learning algorithm.
And while this method works for people of all ages, it's especially effective for young people.
