if you freeze up in interviews, are you also going to freeze up in developer meetings? Are you really saying that your developer meetings are as high-stakes as job interviews?

Re: I will not do a tech interview
#162Meeting potential employers outside the office like this (over lunch or coffee) has been so much more effective for me as well. It takes the pressure off on both sides and lets everyone really get to know each other. If you can't sit down with someone over coffee or lunch, how are you going to work with them?
We're gathering companies who are interested in this approach to hiring (and trying to make it a trend). Employees at the companies offer coffee meetings (their treat) that anyone interested in the company can request. If there's mutual interest, they meet for coffee to chat about the company.

I'll try to turn the table on you. Pick some particular technology that you don't hold in your head. three.js, Angular, Bootstrap, canvas, WebRT - whatever. I'm sure among those we'll find some details you don't have in your head right now and you will look up some APIs/details. Now I'll structure my interview around those topics which I happen to hold in my head since we use them all the time. I am not a front-end w…

Maybe somebody can explain this better to me -- but if you freeze up in interviews, are you also going to freeze up in developer meetings? During code reviews? When you're in the room with clients? Of course not. Interview situations are very, very different than the others. Meetings and code reviews are with co-workers, whom you know and trust. Meetings with clients could be nerve-wracking for other reasons, but the…
With a client, it's about the software you're developing, with a interviewer, it's about software architecture or coding principles.
In your example about HTML -> CSS I think you missed the point. It wasn't so much to check that you have something memorized, but to check your familiarity with the subject. Everyone sits with a browser while they code - I don't think that's a unique workflow. The thing is, if you've done this HTML -> CSS conversion a hundred times before, you wouldn't need to look it up. They're trying to gauge your experience level and if you've done this stuff hundreds of times before. I bet even a highschool student could find that with Google.
EDIT: I think a more relatable example would be if the interview gave you a simple geometrical problem and you were upset you can't look up the Pythagorean theorem. You're not being tested on your ability to memorize the Pythagorean theorem per se - it's just that everyone is expected to know the Pythagorean theorem b/c it's so fundamental to the sciences. Super simple problem with no google are testing if you have domain familiarity and experience and are a metric of whether you will hit the ground running or not. They're not gauging you problem solving ability, or your ability to memorize crap.
Re: I will not do a tech interview
#165Not quite the same, but I once had a no name company (getglue) tell me that I need to do a 3-hour programming assignment before I can interview with them. I have too much self-respect for myself to put myself through that process. I declined the "opportunity" to interview with them. The interview process is broken and many of the interviewing techniques either do not correctly judge a candidate, or place too much bur…
I once had a no name company (getglue) tell me that I need to do a 3-hour programming assignment before I can interview with them In that case, I would think I was the subject of a psychological experiment entitled, "How far can we push developers". Although it would be tempting to accept the offer and then write whatever code they asked for in QuickBasic 4.5 (circa 1988) telling them they need to use something more…
I've only ever answered one interview question in Scheme, the problem was perfect for it. :) I first had to check if the interviewer knew Scheme, and he did!
I fear it has been long enough that I could not repeat such a stunt now days, but last week a resume came by my desk that had LISP listed on it, so I prepared some problems that would be trivial in LISP just in case. Unfortunately it was as I had suspected, a stale language listing that should have been removed from the resume long ago.

Truthfully, I'm not certain I'd trust someone who can go through an interview without freezing up or having any similar problems. Confidence is a valuable thing, but only in moderation.

How exactly? Freezing up in a meeting can get you fired just like freezing up in an interview can get you turned down for the job. Sure, you'll get comfortable with your coworkers, and they'll get more forgiving of temporarily lapses, but I think most interviewers (for non-terrible jobs especially) purposefully give some extra leeway to interviewees, since it's understandable for them to be a bit more nervous than a coworker would be.

Personal anecdote/case study:
I interned on the frontend team at Mixpanel in 2011. I had written about 200 lines of Javascript prior to starting work, not a ton of HTML, and literally no CSS. I had however done quite a bit with Python/Django (which they used). My first month consisted of me "getting up to speed" where I was working at a lower rate than others on the team. By the end of summer, I was a fairly productive member of the (3 person) team, building products with tools I had previously had very little experience in.
Fast forward 2+ years:
I've now done 2 years of college. I spent one summer writing distributed machine learning tools for fraud detection, and another summer during deep learning research. The majority of my computer science classes are just theory (no programming), but I've done a bit of programming in C/Python/Rust (for a choose your own language thing) for school and also a bit of programming in Python on the side. Now I apply for your frontend job.
>I'm going to ask them to explain how a closure works
Closes over internal state, talk about read-only (Python)/ read/write (JS) closures and how read/write closures allow you to make basic objects out of functions.
>How they deal with AJAX
Use a callback? Not sure what this question is really asking. Potentially do some kind of client side queuing for some special cases. How to implement server-side push is more interesting.
> What they think about "!important".
Overrides all other CSS rules iirc. Not a best practice thing to use, but still a useful hack to keep in the toolbox.
> Things to be careful about with floats.
I don't remember specifics, but I remember floats can be a bitch. Just Google any problems I'm having. I believe the type of container that floats are in matters.
> How CSS precedence/specificity works.
Could probably work out an example. In general, element inherits all rules that apply to it, and more specific rules overwrite less specific rules. I don't remember the non-trivial ordering for more specific -> less specific (ie id is more specific than class), but would be very easy to look up.
> How to architect a webapp
Would be more comfortable talking about the server-side component, but could talk about client-side code design.
Summary: I'd probably do alright but not exceptionally on your interview. You might give someone else the job. They would probably be more productive on day 1, but I don't know about by the end of week 1.
The twist: If I was interviewing for a frontend job, I'd take a few days to study all of this stuff and significantly increase my interview performance. Would that make me any better at actually doing the job? Probably marginally.

Just replying to state my shock at how many people are defending poor interview performance. If you freeze up during interviews because it's "high stress" then maybe you need to practice going on more interviews until it doesn't bug you any more. When you're a developer -- especially at a senior level -- you need to be able to work well under stress. Hell -- you need to be able to do that for nearly any job in the wo…
Add to that the fact that most tech interviews are held in non-real world situations and it's easy to see why some people have problems. Putting a person in a room with a piece of paper with a chunk of code that has a 'hidden' flaw with no access to any other resources isn't real-world.
All of us have access to books, manuals, the code, google, any number of places we can use to help.
And usually these interviews focus on nuances of a language or a programming trick that you only know if you've seen it before or encounter it regularly.
The codebase I'm working on now targets the iPad. If I were to interview with a company and the tech reviewer asked me about an IE specific hack chances are it would take me a while to come up with it. Assuming I've encountered it before.

#170Let's do the opposite of all these things!
I've recently started writing down an attempt at providing a better replacement I hope to begin following and enforcing 100% without exception going forward. My own system has similarities to what the OA advocated. I call mine RYR, which stands for "Realistic, Yes-Finding and Reciprocal."
