| 00:00.17 | keldwud | oh, I had to split a string and then output the longest word in the string |
| 00:00.37 | keldwud | and apparently I fail so hard that I can't even do that |
| 00:00.43 | SunSparc | I am at the point where I enjoy both of them. But it depends on what I am doing with them. I really like Go for standalone apps, APIs, service, etc. I tend to use python for devops stuff. |
| 00:00.44 | joshh | online or in front of someone? |
| 00:00.44 | keldwud | I was able to do it in bash from the command line |
| 00:01.00 | keldwud | fortunately it wasn't in front of someone, but I still failed, it was a pre-recorded interview |
| 00:01.14 | keldwud | they provided a sublime-like interface online for the programming portion |
| 00:01.20 | joshh | was it coderpad? |
| 00:01.42 | keldwud | not sure |
| 00:02.11 | joshh | show your bash solution |
| 00:02.23 | joshh | curious about that |
| 00:02.29 | keldwud | for the follow up interview question (uses your webcam and you answer the questions via webcam recording) I admitted to failing in both python *and* bash |
| 00:02.47 | joshh | what kind of job role was it for |
| 00:02.51 | joshh | real programming or ops? |
| 00:02.54 | keldwud | ops |
| 00:03.09 | keldwud | this is as far as I got in bash |
| 00:03.09 | keldwud | http://pastie.org/10672324 |
| 00:03.18 | keldwud | with the #!/bin/bash of course |
| 00:03.32 | keldwud | I wasn't closing my statements properly |
| 00:03.57 | keldwud | and I think because I was going back and forth between bash and python, I ended up using the wrong characters in some places |
| 00:04.05 | keldwud | and got my semicolons and colons mixed up |
| 00:04.26 | joshh | was it good other than syntax? |
| 00:04.35 | keldwud | probably not |
| 00:04.36 | keldwud | lol |
| 00:06.02 | keldwud | this seemed to work alright in python with a predefined string |
| 00:06.02 | keldwud | http://pastie.org/10672327 |
| 00:07.57 | jlp_znc | read s; echo $s | tr ' ' '\012' | while read word; do l=`echo $word | wc -c`; echo $l $word; done | sort -n | tail -1 | awk '{print $2}' |
| 00:09.33 | jlp_znc | I hate canned quizzes like that, where you can't ask any questions. for example, I'd ask "so, do I care about punctuation?" |
| 00:11.19 | keldwud | interviews take a lot out of my self confidence |
| 00:11.23 | jlp_znc | my favorite that I got asked at google was to count the words in a file and print out the words and number of times they exist. tr ' ' '\012' file | sort | uniq -c |
| 00:11.46 | jlp_znc | the dude interviewing me had never heard of uniq |
| 00:12.53 | programmerq | ha! |
| 00:13.01 | programmerq | uniq is pretty useful |
| 00:13.23 | programmerq | my blind spot is the 'cut' command. I never really use it unless I'm pasting someone else's command |
| 00:13.38 | programmerq | awk I only know print |
| 00:13.44 | programmerq | sed, I only do s///g |
| 00:13.52 | programmerq | but I know both commands can do so much more |
| 00:15.06 | jlp_znc | I never use cut, because BSD didn't have it back when I was learning this stuff. I always use awk for that kind of stuff. |
| 00:15.23 | jlp_znc | cut would probably be better in a lot of cases... not nearly as heavy as awk. |
| 00:15.42 | jlp_znc | in general, once I hit about 10 commands or so, I rewrite it in perl (often right on the command line with perl -e) |
| 00:16.21 | jlp_znc | if I had a shell on a machine, I could look at the cut help and then probably use it more. |
| 00:18.21 | keldwud | I use cut when it's a one-off |
| 00:18.53 | keldwud | my problem is that I have yet to hit 10 or more commands in my pipes, so I am still stuck doing everything from the command line |
| 00:19.42 | joshh | ya the python paste is a bit odd |
| 00:21.15 | keldwud | oh that was my old one, forgot to include my text.split line |
| 00:21.16 | jlp_znc | can you do fizz buzz? we had an interiew for a guy (for an SRE position at linkedin) where he couldn't get fizz buzz right in an hour even with coaching. |
| 00:21.33 | keldwud | I haven't done fizz buzz in a few years |
| 00:21.40 | jlp_znc | (we called it "linked in" instead of "fizz buzz", but it was basically the same thing) |
| 00:21.43 | keldwud | I'm afraid that if I tried, I'd probably get it wrong |
| 00:21.46 | jlp_znc | :-/ |
| 00:21.58 | keldwud | I'm a horrible admin! |
| 00:22.08 | jlp_znc | sounds like you need to work on some codey skills. but not all admins code, you know. |
| 00:22.26 | keldwud | yeah, I haven't had many opportunities to work on my coding skills lately |
| 00:22.32 | keldwud | lol enterprise fizz buzz |
| 00:22.49 | jlp_znc | had a battle today trying to get ODBC working with python on a co-worker's mac. was working on mine, but not on his. we ended up uninstalling everything and reinstalling. ugh. |
| 00:23.02 | joshh | http://pastie.org/10672354 |
| 00:23.22 | joshh | fizzbuzz is still fairly common in ops interviews i think, as well as stuff like nth fibonacci recursively |
| 00:23.40 | keldwud | yeah I forgot the recursive fibonacci one, too |
| 00:23.43 | jlp_znc | joshh: you should cache the length of longest... then you don't have to count it every time through the loop. |
| 00:23.46 | joshh | there are like 40-50, if not less, extremely common coding interview questions that job hunters can work on studying and pass almost anywhere |
| 00:24.52 | jlp_znc | my favorite part of the interview at linkedin was the "debug this" test. live web server (on a VM) that was doing ... odd things. |
| 00:25.18 | jfindlay | programmerq: unicode doesn't even work in py3, where by default, all strings are utf-8 encoded |
| 00:25.26 | joshh | ya i detest normal coding interviews and enjoy stuff like that |
| 00:25.33 | jlp_znc | I got stuck on the 4th part, where I knew what had to be going on, but couldn't tell how to "fix" it. then the interviewer said "all I can tell you is that you have everything you need on the VM". |
| 00:25.50 | jlp_znc | sure enough, source for the web server was on there. found the offending line (an assert!) and fixed. |
| 00:26.07 | joshh | was it an assertionerror? |
| 00:26.10 | jlp_znc | yep |
| 00:26.15 | joshh | python webserver? |
| 00:26.25 | jlp_znc | it was asserting that the page it was sending wasn't named something in particular. apache. |
| 00:26.38 | joshh | that's cool to check for basic reading and understanding skills |
| 00:26.58 | jlp_znc | and debugging. I found the problem with gdb. didn't realize I had source code until prompted. |
| 00:27.14 | jlp_znc | removed the assert, recompiled, boom. worked. |
| 00:27.17 | joshh | ah, apache would be a little tougher |
| 00:27.21 | joshh | what was your linkedin job? |
| 00:27.23 | jlp_znc | he said most people didn't get that far. |
| 00:27.28 | jlp_znc | Senior SRE |
| 00:27.36 | joshh | didn't think C/gdb/etc would be that common for most SRE roles |
| 00:27.55 | jlp_znc | no, it's not. especially not at linkedin (where most stuff is in python or java) |
| 00:28.06 | jlp_znc | but they were more looking at how you figured out a problem. |
| 00:28.32 | jlp_znc | crap, it's 5:30! I've got to bail. see you guys later. |
| 00:28.54 | joshh | later |
| 00:31.08 | joshh | keldwud: did they ask you that fibonacci question? |
| 00:46.08 | keldwud | joshh, nope |
| 00:46.10 | keldwud | I'm glad they didn't |
| 00:46.43 | keldwud | I wish interview questions had config files for you to modify |
| 00:47.12 | keldwud | or asked you to serve up a secure web page from a fresh linux install |
