Interview tales

nice blog do you have an rss feed?

>>59413355
Glad he didn't get the job. He wouldn't have known his employer is such a perverted weeb.

>>59413355
I had a misfortune of interviewing for sysadmin/engineer positions a few times.

It's was either cringy, self taught nerds who knew their shit, indian immigrats who sort of know what they were doing, in a bad english sort of a way, or worst of all, university graduates who have absolutely no clue what they are doing.

I'd start feeling like the kid too if I had a retarded employer use the word "vector" in the same sentence as strings.

What the fuck are you on op? How are you even a developer if you can't make a request that everyone can understand first try?

I'd hate to see the convoluted software you create.

>>59413355
Wait, I'm not getting the job?
>t. Rust user that got interviewed today

>>59413355
Some notable interviews:

1- Guy with 5 years of programming experience. Could not do the 12x12 table. Could not count down from 700 to 200 in decrements of 13.

2- Girl with 1 year of programming experience. Did not know what is the modulus operator.

3- Candidate came to the interview a hour early.

4- Candidate had a phone interview. I always let the candidate choose the time, so the candidate asked for noon. When I called, candidate was on a crowded train where I could barely hear any answers.

5- Candidate passed the phone interview. Scheduled a face-to-face interview, also at noon. Candidate cancelled it... at 11:55am.

Non-interview oddities:

1- Candidate sent us a shirtless picture in resume (male candidate)

2- Candidate included blood type in resume

People are weird.

>>59413758
I obviously didn't say vector during the interview, I wrote out exactly what I was going to give him on the white board.

Control your autism.

There's no middle ground

>>59413355
>vector of strings
Is it different from "array of strings" or "collection of strings"?
From what I understood you tasked him with something like removing duplicate database entries(because somebody could make a mistake while adding things or something).

Wait, what? Why did you ask him for that?

>>59414423
Exactly the same thing, we just tend to call it a vector where I work. I of course explained its a sequence of strings in an abstract way because I had no idea how Rust would store it.

>>59414449
>Why did you ask him for that?
Me: Hello! We are hiring. Do you know programming?
Him: Yes! I have 5 years of experience!
Me: Cool! I have a few questions for you to test your programming skills! Let us start with the EASIEST TWO QUESTIONS! This should take just 1-2 minutes each!

I'm surprised he'd pass screening to be honest.

>>59414490
That doesnt answer the question

>>59414479
I just realised I don't remember writing a custom fuction to remove duplicates, never been taught that. The last time I had to to such task was done with Edit-Permute Lines-Unique.
When I start to think about it, I see bubble sort style loop as a solution. Or sort it all anyhow and run through the array once to check neighbouring members but it all would seem to run very slow.

>>59414511
Me: Hello! In ANY LANGUAGE THAT YOU ARE COMFORTABLE WITH, write some code that will output the 12x12 table.
Him: Uh...err.... ummm...

-I interrupt-
Me: Perhaps you can shorten this by using loops. It would take you a pretty long time if you use this method and I changed the question to 100x100 table, no?
Him: Oh... ah... umm... err....
-30 minutes later-
Him: I cannot do this.

>>59414543
I asked him to give me solutions to some simple programming questions, in order to gauge his programming capabilities.

>>59414564
I could give away the solution since it's not a programming thread, but I really like this question and I don't want candidates to rock up with a solution in hand. But I'll say you can do it in linear time with a single scan to find duplicates and a second scan to remove them

Yes, most definitely.

>>59416948
I don't know shit about programming. I wanna start with perl for web or c++. Where can I go to get questions interviewers would ask so I could get hired easily.

>>59417039
Big companies will ask you dumb shit about data structures like making a doubly linked list or a binary tree from scratch.

>>59413758
>>59414124
Wait, what? That's what the thing is called. Why would you go all wide-eyed on something as basic as this?

>>59414652
Math has nothing to do with it. It's the name of one of the most common data structures.

>>59414617
>99.5% of programming grads looking for a job cannot program at all.
That's not actually true. The vast majority of graduates can solve these exercises just fine.

Rather, what is going on is that a large percentage of INTERVIEWEES can't answer this question. The reason is simple: there are some people out there trying to get programming jobs without any of the necessary skills or qualifications. These people never get any jobs, and then they KEEP interviewing, which means they make up a very large proportion of interview candidates even if they only make up a small proportion of the people in the job market.

>>59414564
Honestly, if this takes you more than zero thought, you should practice your fundamentals more.

>>59417262
>Math has nothing to do with it. It's the name of one of the most common data structures.
Actually, the real name is dynamic array. Who knows what idiots came up with vector in C++.

>>59417608
A dynamic array is a different thing than a vector, anon.

A dynamic array is a very simple construction consisting of a pointer to an allocated array, and a capacity counter. It can resize itself, and can access any of its elements in constant time.

A vector is a (slightly) higher-level data structure built on top of a dynamic array, that models a *sequence*. It consists of a dynamic array plus a length field (and optionally a start field). It has meaningful contents only in the start -- start+length range, and has operations such as `append`, but not operations like `write to item length+3`. It auto-resizes according to some specific resizing scheme that provides amortized constant-time behavior, and all that good stuff.

Yes, the vector is a pretty thin layer on top of the dynamic array. But conceptually they are different things; a dynamic array implements a generalization of an array (in the sense of a chunk of random-access memory), a vector implements a sequence, which has different meaningful operations and involves different cleverness on top of the dynamic array abstraction. Other array-backed data structures, such as circular buffers or hashtables, are built on top of dynamic arrays -- not on top of vectors.

>>59413355
Can you lost some common programming exercises you would give to a person you're interviewing? It would be really helpful so I'm not blindsided when I go in for an interview.

>university graduates who have absolutely no clue what they are doing
I'd shit on the education system for making universities be highschool-tier in recent years, but the truth is that if you don't have self-taught skills then you will probably be a very shitty software engineer. Programmers who don't have the drive to teach themselves new skills related to their job probably expect Stack Overflow abuse to fix everything, which is a bad mindset to have when you're in a position that's not so easy to outsource and have to come up with solutions yourself to problems that no one knows how to solve yet.

-guy told me about his sex fetishes with cartoons
-guy literally refused to say anything at all, like was afraid of it or something. Everything was fine up to that point but then I thought he was going to cry

Most of it is a pep talk for the interview, then the real meat is in the exercises and solutions. It contains hints like you'd receive in the interview.

It's about as useful as how seriously you take it. A previous version of it helped me immensely.

>>59413355
I seriously hope this is a troll. OP is no way fit to interview someone. using a term like vector, which is a c++ library reference for a list has different meaning in maths and physics.

As for your candidate, depending on the interviewer they might be looking at different things. Someone at Google will be looking to see if they understand computer science and can get the problem done faster. A start up will be looking to see if they can use frameworks to not reinvent the wheel. You failed to give proper instructions because you're a retard.

If you think he wanted you to call a built in function to do the job when he clearly wants you to make a for loop and explain your logical reasoning for the implementation clearly, you're completely autistic.

>well he shouldn't ask dumb questions

I hope every interview includes these stupid questions just to weed out these fucking autismo's

>>59417608
If the interviewee can't handle a slightly unclear question, they don't deserve the job.

If they don't know what a vector is that's probably fine, they can ask. If they don't ask then there's an issue.

if the interviewee expects everyone to change terms to suit them then they don't deserve the job.


If any interviewee argues like this thread is currently doing they surely are autistic.

Why don't you tell them you can't find a single qualified grad?
They probably don't realize you passed up 30 good candidates because they didn't have an unrelated degree.

Haven't actually ever had to pass a technical interview since I always got positions by having relations in companies who knew I was competent. From what I can read in the different threads it's very stressful though, even though most interview questions seem easy to me (even from Google and the likes) I wonder if interviewers acting chill don't contribute to making the interviewee feel helpless in some situations.

>>59431176
A PR girl and a chairman were in the room at all times, as usual.

Impossible. Rearanging in memory would be sorting wich is at best nlogn.

Linear is possible with just inserting into a hashtable but that would require additional memory =overhead.
