  1. From 0 to 100 in 3 months* A story of

    an engineer lost in the hiring process
 *a little bit longer, but I like number 3
  2. Experienced Multifunctional Software Engineer Sergey Kibish https://sergeykibish.com sergey@kibish.com Skilled in

    different languages / tools / technologies. Strong engineering professional with a Master of Science (Mg.Sc.Comp.) focused in Computer Science. Natural-born leader, full of passion and charisma. A hobby is music in all of its manifestations (listening, playing, writing). @s_kibish
  3. Motivation / Goal I really want you to think one

    more time about your interview process. Is it really good? Or you just do it, because you are a robot and don’t see any problems? After this talk you should have a will to change your interview process and how your view the candidates
  4. Disclaimer

  5. Disclaimer This is a rage talk. If I will swear,

    I’m sorry. I will try not to This talk is based on my personal experience. Something applied here might not work in your environment
  6. Story time

  7. Once upon a time, team of engineers was asked a

    question “Who want to help with interviews?” And only one hand raised up This was beginning of the end At some point it was like…
  8. None
  9. Facts • More than 200 interviews in total • More

    than 110 interviews done only by me • On average 12 interviews a week (it’s up to 4-5 interviews in some days) • Boys and Girls • From around the world • Online
  10. Why • New big shiny project was on the horizon

    • Workforce was needed • Office in a new location was opened • Company committed to provide 200100 engineers before the end of this year
  11. Recap Don’t sign contracts where is specified how many people

    you should provide. Success of your project is not about amount of people, but about quality of the work done
  12. Interview process

  13. In the beginning • Just check that person know something.

    General questions on understanding of things. • Interview — 1h long Agencies Interview Offer
  14. Recap • Such scheme will work only if agencies invite

    people that are really what you expect (which is, obviously, impossible) • Interview process is short. People do not expect to get offer right away and they think that something is wrong here • Because interviews are simple, it is difficult to check that it is not a cheater in front of you • I started to burnout
  15. In the middle • All from the beginning • Additional

    team members started to participate in the interviews from time to time
  16. In the middle

  17. In the middle • All from the beginning • Additional

    team members started to participate in the interviews from time to time • Classification

    terminology • Middle — depth of knowledge • Senior — T-shaped knowledge, architectural intuition
  20. Classification • Self-sufficiency • Junior — requires help from teammates

    “code review” and “open ended” questions Agencies Interview Offer Internal CV screening
  23. Code review

  24. Open-ended • What do you love/hate about [technology]? • You’ve

    implemented a feature. How you will make sure, that it is working as expected?
  25. Recap • Less false positives with the candidates • Cheaters

    are recognised better • Problem to figure out seniority
  26. Current state Agencies Interview Offer Internal CV screening Homework Review

    Interview 2
  27. Homework • Should be something simple and connected with your

    domain in some sense. Should be real and not an algorithmic quiz. • Mandatory and additional requirements • Deadline is set by the candidate • Discuss homework on the second interview
  28. None
  29. Recap • Have a list of requirements for yourself —

    what do you expect from the candidate. Create avatar • Don’t send junk info to agencies • Tell candidate about your hiring process (respect time) • Homework is only for seniors • Timing: less than a week • Live coding interviews don’t work
