D2L Software Engineer Customizations interview questions

First got a 45 minute phone interview which consisted of resume, behavioral, and technical questions. Got a reply back a couple days later for an in-person interview. The in-person was 1 hour long. Half an hour consisted of resume discussion, and the other half was technical questions. The technical part consisted of 2 questions - the first question I was given a page of code and was asked to find things I would change (try/catch exceptions, public to private variables, etc.). The second question was "How would you design a deck of cards" and "how would you shuffle a deck of cards?". Got a reply back a few days later saying I did not get the job.
