TooMuchAbstraction posted:I may need to start explicitly asking candidates to use pseudocode. Usually I ask them to use whatever language they're most comfortable with, but sometimes that leads to a candidate deciding to do, say, manual string parsing in C. Which is a signal of a sort, but not really the kind I'm looking for when interviewing. Good post/username combo. I think requiring pseudocode is not a great plan, but you could say "please use bison or some other parser-generator" or "please use a language with a decent regex library". I'm doing SRE interviews and a lot of candidates want to solve literally everything with a bash script. Most of the time, as you say, this is enough of a signal. (I think "this is not the candidate you want to hire" is exactly the signal you should be looking for when hiring.) But occasionally they're just being a bit too lazy/clever and will do a nice job in Python or whatever when prompted. (I tell them "anything except bash". One day someone will respond with csh.)

JawnV6 posted:I think you should be saying more words at the beginning if you routinely go through the phone screen, arrange the time and effort for an onsite, all for you to watch them irrevocably faceplant in the first 5 minutes on language selection. Exactly how many candidates have you rejected on this basis? I don't reject them on the basis of language choice. Like I said, it's a signal of sorts but not really a useful one. What I really want to see is someone who can come up with a workable algorithm, which requires only the ability to talk about loops, conditionals, data structures, etc; nothing specific to language choice. The coding is secondary, really. Someone who can come up with a solid algorithm but then runs into trouble because they made a bad language choice will still pass the interview, they'll just take long enough that I probably won't have the chance to really plumb the depths of their capabilities. So someone that might be a "holy poo poo hire this person ASAP" might end up just being a "they clearly understand what they're doing and they did a decent job." And someone who is "they're basically OK, came up with a workable algorithm and coded it out" becomes "they're basically OK, came up with a workable algorithm but ran out of time implementing it." What has happened a few times is that I'll get the combination of bad language choice with "immediately started writing a for loop before they'd even figured out how they were going to solve the problem." If you do that in an expressive language, you should (hopefully!) fairly quickly figure out that there's some subtleties in the problem that you need to address, so you can back up and deal with those. If you're in a language like C, though, you can spend so much time tediously writing out boilerplate / dealing with limited data structures that by the time you figure out your approach is flawed you won't have time to fix it. I'm still trying to figure out how to head that off without giving them enough hints that my evaluation is thrown off. In any case, my interview is only one of many, and my evaluation will include any appropriate weasel words like "I had the last interview of the day; candidate seemed tired/nervous; we spent the first five minutes going to the restroom".

If you're happy to hire a candidate who can only use C then it sounds like your interview question, which is terrible when done with C, is a bad interview question. There's lots of algorithms questions that work great in C. Ordered insertion into a linked list? Write a regex matcher for a simplified regex language? I donno. What kind of algorithm knowledge are you trying to test for?

It's definitely a bad fit if the candidate chooses to use C, but it's rare to see a candidate that only lists C on their resume. And also pretty rare to see candidates that don't list either C or C++, for that matter. So I can't reliably choose an interview question based on the resume alone. I guess I could walk into the interview with two questions prepped, ask the candidate what language they use, then choose a question accordingly, but I honestly haven't felt like it was that big of a problem. Algorithms interviews are generally "I want to see how you approach problems that you almost certainly haven't seen before." This isn't about being able to regurgitate Dijkstra's algorithm on command, or knowing how to use dynamic programming. My favored question can fairly easily be solved without anything more complicated than a list. It's "here's a problem, there's several valid ways to solve it, what are you going to do and more importantly why?" That's why I emphasized that good candidates will be able to come up with a convincing solution before they start coding, and that the actual code is secondary. It's also why the lead-off of this conversation was me musing that maybe I should tell all candidates that I want them to write in pseudocode, in an attempt to remove "language of choice" as a variable in the interview process.

Had my third of a four(?) step interview process at a company today. I didn't beef it but true to form I didn't get a lot of sleep due to nervousness so I'm sure I didn't wow them either. This puts me at just over three hours (all remote) with ~6 to go (on-site) for this one company. No they aren't Google and I don't expect them to offer a Google-level compensation package. I feel bad about putting up with it, but I want out of my current place and it'll end up being a lot of practice interviewing that I can certainly use. Sorry to everyone for moving the needle, however slightly, in the direction of "ridiculous" vis-a-vis amount of time an interview should take. I think I need to spend more of my free time just going to meetups and poo poo. I don't like spending my free time coding, but it'd be nice to just get hired via friendships instead of running the goddamned gauntlet.

I didn't beef it but true to form I didn't get a lot of sleep due to nervousness so I'm sure I didn't wow them either. Generally just try to show that you were awake during your CS classes (or self-teaching), that you can think, and clearly articulate your thought process. Obviously every company is different, but many times you can get quite a lot of "partial credit." I've been in debriefs and given feedback like "the candidate got 90% of the way there and I'm positive she would have aced it with access to a search engine. Hire." Another good signal is that your prospective employer doesn't like sunk costs anymore than you do, so having gotten as far as you have in their process means you're in a strong position to succeed. And try to have fun with it. I know that's easier said than done, but presenting an enthusiastic and pleasant personality in a stressful circumstance is a trait your interviewer will appreciate. Building your network is never a bad idea either. Good luck to you!

Thanks! Yeah that's all generally the approach I try to take. There's no way for me to stop the pre-interview anxiety except to just keep interviewing so it becomes old hat, but I've never just frozen or clammed up in an actual interview (which I've seen happen to plenty of candidates). The anticipation is always worse for me.

Pollyanna posted:Oh man, dish. Basically boils down to this: Management - "We're going to spend a year getting 8 developers to build this really great mobile app that allows users to get a subscription that unlocks content in our other apps." Me - "Apple's submission guidelines very specifically state that in-app purchases can't unlock content in other apps. This will end poorly." Management - "Well, Disney gets away with it, so we'll just do it and submit, and if they complain we'll make our case" We built the app, at the end I worked about a month doing ~90h weeks to meet deadline. We submitted and it was approved, but in the first couple of weeks after it went live, Apple discovered the content unlocking functionality. They told us we needed to remove the functionality within a certain timeframe. I was initially instructed to ~ignore this directive~, but when Apple came back and said "hey you guys, remove this or we'll shut down your entire account," the galaxy brain behind this whole scheme decided to meet with Apple and argue with them. When he pointed out that Disney did the exact same thing, Apple said "we don't discuss other cases." While they didn't come right out and say it, Apple let Disney do it because they're a big company that makes Apple a boatload of money. Us... not so much. In any case, Apple didn't budge, but Mr Galaxy Brain would. not. let. it. go. He ended up ruining our relationship with Apple, and our app feature placements dried up literally overnight. No feature placement meant rapidly dwindling revenue, and we ended up shuttering about a year later.

A recruiter from IBM reached out to me and after some conversation told me that the one thing IBM could offer me over my current position was that "IBM cares about employee development, you can do so much training." He could not specify how much of that training was online video courses and how much I had to do in my own time. That was all he could offer, video training in my own time for lower pay. And o yeah, you will be working on client projects at the client site and no, we cannot tell you yet who that client is or what location that would be. How is that appealing? To whom is that appealing?

I would caution also being paid enough money to retire in a year from IBM - there's a rather high chance you get let go within a year anyway. And if you're not let go that early there's a pretty high likelihood it's because you're being paid under market.

Jose Valasquez posted:What do you do for candidates that don't code in their free time Most candidates ask their employers for permission to share code samples if they don't code in their free time, and in addition, many interviewees are internal to my company which eliminates the IP concern. In the rare case a candidate doesn't have rights via any of those avenues, I don't count it against them and we go another way, but that rarely happens. I only do this for those applying to Sr. level positions or above, btw. I don't expect a fresh college hire to bring code.

Hughlander posted:Why’s that? They just spent the last 4 years writing code they have the copyright to. The college applicants I tend to get are already visibly/audibly nervous and I don't want to derail them by forcing them to talk through code in a collaborative work environment they might not have experienced yet. Depends on the type of internships/student jobs they've had, I had an internship where they tossed me in a corner and checked in once a week, and another where I actually felt like part of a team. Potential for growth is more important than immediate production for fresh college hires in my work culture. They aren't getting paid poo poo relative to a senior, and if they turn out to suck they'll be weeded out before they start getting paid more. So, I look for general intelligence, disposition, and ability to form/communicate opinions about software (so did you happen to take any classes on <X technology that my team uses> ? Oh yeah, what do you think of <X technology>? we really like it because of <Y>.) But, the code-sharing approach could totally work for college hires, just haven't done it myself.

An opinionated guide to evaluating candidates with no industry experience based on academic credentials: An undergrad degree in CS is observably worthless, so you should just treat them like a smart person that went to a boot camp or self taught or something. Run them through your process and be fair. A masters is actually negative signal. It's usually just some con artist who thinks that wasting another year and a half in school is going to bring the big bucks. And it's kind of true, but if you want someone who actually gets things done then hard pass. PhDs are another matter. If they're from a good program then effectively they actually do have industry experience, it's just been at slave labor rates while their advisor steals all the credit. If you think they are going to be a good fit, then joking about this will virtually guarantee they accept your offer.

Run them through your process and be fair. My anecdotal experience at non-tech companies disagrees with this. People with CS degrees have generally been quite a bit better at programming and software design than people without a CS degree. There are outliers both ways but a CS degree has been a strong positive signal in my experience. In my experience this difference disappears at big tech companies because there is a higher baseline technical competency.
