Hello Blind community. I have a Data Engineer onsite interview at FB next week. I would like to know the kind of Python questions that one can expect in onsite rounds. Will they be independent Python questions (leetcode easy/medium) or related to the case study/product sense? Any info on this is appreciated. Thanks in advance.
Leetcode medium questions.
Related to case study.
Could you please provide an example?
How was your interview? Mind sharing some details
Example use case: posts numbers dramatic decrease. Discuss reasons why...i.e is it platform specific (android vs iphone) is it region or location specific? How would you track the issue. Are there any users who tried to make a post and failed. Which step did the users fail at?
For coding: it would be some data set related to the use case. For example parsing logs data to see which steps the users are failing at. Then calculate a bunch of running averages from streams to see which ones are below the average...
I have my onsite interview coming soon for the DE position..would you be able to provide me with the sample problem and their solutions.. willing to pay you $100.. DM me to discuss
Product sense is usually generic knowledge and how you verbally analyze/discuss the issue to come up with a solution. The coding would be mostly around parsing data. Lists or dictionaries in python. I dont know if you’re encouraged to use librairies like pandas or numpy in python.
Another example: designing uber surge functionality. Which data points would you track. Build a model...what data types and why.
