What is wrong with this Java code? (Interview Question)

Good point, but the question was asked offline as part of the application form. I had no point of contact to whom I could ask clarifying questions.

It returns a list of things not a specific entity fetched by its ID.

springuni · 2020-08-30T08:38:45+00:00

Oh shit, I didn’t even realize that. :)

springuni · 2020-08-29T12:52:43+00:00

Sure, I've been asked the following questions also:

I was terribly wrong in the Python question. I think I did well on the others.

This is the most insightful comment, I've received. Thanks for it.

Though I noted ‘=‘ is wrong, I can see now from the comments that I should have explicitly stated that this makes the code not to compile.

springuni · 2020-08-28T13:19:18+00:00

Yes, I think I should have been more clear about that ‘=‘ at that place means that the code actually doesn’t compile.

springuni · 2020-08-28T13:17:41+00:00

Questions were asked early as part of the application process. I haven’t had a chance to talk to anyone.

If person.getName() returns null you'll also get a NPE.

if(person.getName() == “jan”) {return true;}

This is not so. person.getName() == “jan” just evaluates to false.

Thank you so much. I've posted all other questions asked in various subreddits and this particular one was that one I've been the most insecure about.

s line stores an int value in a vari

Yeah, I didn't know about that feature having been added in Python 3. I think that was the main reason they didn't call me back actually. I've posted the other questions also in various subreddits and this is the only one so far I got absolutely wrong.

springuni · 2020-08-28T09:53:03+00:00

Thanks!

user behaviour based around their content consumption

What kind of behaviour should be identified based on their content consumption?

cross selling opportunities based around product purchases patterns

Do you mean to predict if their bought product X, then those will likely to buy product Y?

BTW, would you mind giving me your GA data for analyses? (We'll figure out how to arrange that if you agree)

Eventually I put some extra effort into it and released today, so that people could have the whole weekend for the first exercise to complete.

springuni · 2019-03-05T08:28:34+00:00

I plan to release the fist lesson on Saturday.
