Thank you for your feedback. As this role is at a Senior c# Software Engineer level both the questions and time taken to solve them are aligned with that level of proficiency. The test framework we used is utilised by over 1400 companies (Fortune 500 and others). We have gone through the test ourselves and completed this in under an hour, hence our views of what is a reasonable time estimate. We are very sorry that your experience was not as expected. We always strive for the best candidate experience and reach out to everyone individually, especially after an interview has taken place. If that indeed has not been the case please feel free to contact me directly on rlockerbie@commvault.com and I will be happy to share the results of the test with you.
