System design interview questions for IT companies

This is awesome, thanks! The "highscalability.com" posts are so fun to read.

EDIT - correction

Leave the testing until the end? Is that best practice in some places still?

What testing, we'll let the end-user find the bugs and then fix them in the next version.

Reading a bunch of random tech articles makes someone capable of designing systems, now? I don’t think so. Without years of hands-on experience, the odds are that they’ll just design a pile of mud.

Things like this are reasons why tech interviews are so difficult. People cram some knowledge and then have the faulty belief that they’re actually capable of something. It’s frankly offensive to people who have been doing it for 20 years.

Juniors tend not to be as good as seniors. Obviously. That’s why you use questions like in the article to kick off a chat during the interview to look for whether someone might be a good junior to understudy a senior. You don’t need to treat it as an exam with an exact answer to find it helpful.
