Overall Satisfaction with CodeSignal

My work does not require me to use CodeSignal. I have been using it to practice coding problems and prepare for my interviews. This has been useful for me to do a guided set of problems belonging to a coding category.


  • It has IDE, which helps you put debugging statements and run code which helps to find bugs or verify results when practicing coding.
  • It also has dedicated Java Spring-related questions that mimic what is being worked on in the real-world (Creating APIs etc.).
  • It definitely lets import/support more libraries than other coding platforms out there.


  • It needs to expand its use case to another actual working environment beyond Java and spring (not sure if it supports everything today).
  • The ones which have 3 or 4 questions to be completed within 1 hour is really bad for people who code in Java and provide a HUGE advantage to people who code in python.
  • Modify the question based on the language chosen; only then the time limit will make sense.
  • Debugging
  • Quick thinking.
  • Practice interviewing.
  • Coding Pattern Practice is positive.
  • When interviewing with Dropbox, I choose Java so took time to complete.
HackerRank is better as it's just one or at max, two questions when asked by companies, whereas code-signal asks for 4 questions in a limited time. It helps you to complete the question and consider all its edge cases instead of jumping around multiple questions. This frequent context switching does not happen in real life, so it should not be considered in the candidate assessment as well.

Do you think CodeSignal delivers good value for the price?


Are you happy with CodeSignal's feature set?


Did CodeSignal live up to sales and marketing promises?


Did implementation of CodeSignal go as expected?

I wasn't involved with the implementation phase

Would you buy CodeSignal again?


It is less suited for the case where one uses Java and has to deal with so much verbosity. Then it makes no sense to compare people who choose java with people who choose Python.
