This satisfies your problem description: def function(unsorted1, unsorted2): return [1, 2, 3] ;-)
That is awesome. I like; "That problem has been solved so I'd Google it". Your answer is faster.
I find code interviewing so nerve-wracking that I'm delaying my transition from another profession into a much-desired full-time programming job. I'm 40 and always aced interviews before I did my first coding interview last year. In my prior career, I literally never had an interview that failed to result in an offer. But I blew my first coding interview both in the interview itself -- in which I repeatedly blanked o…
Here's some stuff to get you started, hope it helps: https://github.com/andreis/interview

People are very diverse, some are fast and chatty, others are quiet and slow. Usually I perceive the fast and chatty types a bit arrogant. Personality and cultural background is probably an influence. Best teams have a great mix. Often caring about the work is more important than having a genius. (Of course people should be competent).
See, we're having trouble even testing for competency. I passed a pen and paper interview recently (did confidently well on coding, blew the SQL part because I had only used APIs and still thought I should put that on the resume) and still got the position. I'm still scared shitless that I'm going to flub day 1 and I've been cramming and exercising basic knowledge for the past two weeks. I'm worried that the test was…
You should commit things to memory the things your memory naturally keeps. If it doesn't it means you aren't using it often enough to bother remembering it. There's so much information I used to keep re-learning and forgetting because I never used it. I finally realized that it was a waste of time.
I guess the problem is when the job you're interviewing for will need vastly (or slightly) different things committed to memory than what your current job does.
I also like something between google and memory: cheatsheets. I have a dev notebook full of checklists and cheatsheets for various technologies I've used and tasks I've done.
> Hi, my name is Aline. I used to code for a living. Now I hire engineers. One of the things I've done that I'm most proud of is Lessons from a year's worth of hiring data, where I showed that, in an engineering resume, pedigree isn't a particularly valuable signal (whereas typos and grammatical errors are) So what happens if you're lystdexic?
Dear software professional: if you have been rejected because of a coding interview, don't feel bad or discouraged. It has little to do with how smart you are. Unfortunately, this style of interviews is likely ineffective and leads to hiring people who look alike and have similar skills. Solving a problem with someone looking over your shoulder and forcing you to talk to explain what you are thinking is a skill that…
The point of these type of interview questions is to see how well you can reason and communicate. It is not to see if you know how to solve that specific problem, and if an interviewer is using it like that then they are not a very good interviewer. A standardized test does not substitute for actually talking to someone while they solve a problem and seeing that they can think logically and communicate those thoughts…
I use this same technique now when interviewing others.

"Solving a problem with someone looking over your shoulder and forcing you to talk to explain what you are thinking" is actually how problems are generally solved in most fields. Software engineering is perhaps one of the lone exceptions, and I think the pair programming movement has a bone or two to pick with your premise.
There's a big difference between someone looking over your shoulder and forcing you to explain what you're thinking, and someone working with you to collaboratively solve problems. In the latter case, you can ask lots of questions and throw out lots of dumb half-baked ideas, and actually get a meaningful, useful response from your partner/pair in response. If you're whiteboard interviewing, good luck getting your int…

Agreed; the idea of hiring a musician without hearing them play would be madness. Not handing me a recording, not discussing intricacies of music theory, but actually playing live. And yet, a talented studio musician may suffer from performance anxiety in this situation. What to do?
I think the best thing is to ask them to warm up with something basic like a scale, and let them work their way up as their comfort level increases. I knew some people who were particularly pleasant and easy going, so they were able to relax people suffering from performance anxiety. There are interviewers who treat coding interviews as a high pressure, adversarial exercise, though. On the other hand, those sorts of…

Right. While I wasn't interviewing for a technical position, the interviewer asked me to 'vote off' one of the 50 U.S. states, and to describe my reasoning why (perhaps this is a common question but I hadn't encountered it before). It was basically an exercise in thinking out loud, with a lot of "well, I'd probably want to first consider x, but actually before doing that I'd want to take into account y...". There was…
