can someone help me how to prepare ? i hate feeling lile a programmimg bot on the livecode and tired or failing those puzzles why cant a company like facebook understand that its all about the attitude of candidate and not how much he knows before you hire him
Definitely the right attitude
Spark java or apache spark?
OP might be referring to this https://sparkar.facebook.com/ar-studio/
Here is my attitude. I'll do exactly what you're telling me to do. I'm a nice guy and will work hard. I will learn what you think needs to be done and work very hard to get everything done. Hire me for attitude.
Guess that’s all is needed isn’t it
Says everything you need to know about Oracle...
How about this i am the greatest developer planet earth can ever see but I listen to none
Read spark the definitive guide. Core spark topics from there such as understand the difference between low-level apis and high-level structured apis. How spark partitions data. Logical planning and physical planning when building the DAG, and the components therein. Narrow vs wide transformations. Sparks lazy evaluation model in terms of transformations and actions. When data is kept in memory and when it's spilled to disk. Different deployment modes when submitting a job and the different spark processes running in a job and how they relate to Yarn resource manager, application master and node manager. Distributed shared variables, ie broadcast variables and accumulators.
Attitude is definitely one thing we look for, and here's another: a decent grasp of English
