Tips and Resources
You cannot stop a section once you’ve begun, make sure you have a good connection and area you can focus in.
The technical assessment itself is 110 minutes to complete 2 coding challenges (90 minutes) and coding approach as well as a System Design module (20 min).
The time remaining will be clearly displayed in the left hand corner of the screen throughout the test. There will be 2 surveys following the assessment; a work style survey (10 min) and feedback survey (5 min).
Some key points to emphasize for the coding questions are as follows:
You can use any of the following languages you’re most comfortable with: C, C++, C++14, C#, Go, Java7, Java8, Javascript, Kotlin, Objective-C, PyPy2, PyPy3, Python 2, Python 3, Ruby, Scala, and Swift.
The assessment has two problems… one is based on data structures, the other is a problem solving question
Focus on solving the problems first. Once you have done so, go back and optimize. Our grading system focuses on the test cases being solved correctly most importantly. Therefore, finish BOTH problems before going back to optimize the code.
Some key points to emphasize for the system design modules:
We want to see your system design skillset applied to a few fictional situations with simulated peers, managers, and stakeholders.
You will not be requested to complete a whiteboarding or a diagram exercise. We simply need you to rate the most effective or ineffective actions to take given the scenario
When responding to these scenarios, put your system design hat on, and employ system design concepts like designing for maintainability, determining tradeoffs, and dealing with ambiguity.
The assessment should take approximately 20 minutes and is untimed.

Run Time Complexity is important; be sure to brush up on Big-O Notation.
You will solve problems like: “Write a Java method to determine if two input strings were an anagram of each other.” Please take time to practice clean code, knowing/using input checks, and finding 'edge cases' like empty strings. Practice finding ways to optimize your code and improving algorithms for solutions so you're finding simple, not complicated answers.
