tdd for hiring

package hiring

type Job interface {
    Define() []Test
    Evaluate(candidate Candidate) bool
    Adapt(feedback Feedback) Job
}

hiring is broken
vague job descriptions
gut-feeling interviews
misaligned expectations
it’s a mess that wastes time, money, and talent
but what if we treated hiring like we treat code?
what if we wrote tests first?

the broken cycle

traditional hiring:

job post -> interviews -> gut feeling -> regret
     ^                                      |
     '--------------------------------------'

stop that cycle
start thinking in tests

tdd hiring flow

tdd hiring:

test -> candidate -> evaluate -> adapt ---.
  ^                                      |
  '--------------------------------------'

why it works

write tests for what matters
technical skills? cultural alignment? problem-solving?
define it before you need it
let your tests evolve
each hire teaches you something
use it, adapt, improve
don’t repeat old mistakes

clarity through tests

tests bring clarity
no more “must be a team player” bullshit
define what that means
make it measurable

failure as data

when candidates fail? that’s data
use it
some failures are warnings
others are blockers
know the difference

the code

type EngineerJob struct {
    Title        string
    Skills       []string
    Experience   int
    Alignment    []Test
    CoreTests    []Test
}

func NewEngineerJob() *EngineerJob {
    return &EngineerJob{
        Title:      "software engineer",
        Skills:     []string{"go", "git", "microservices"},
        Experience: 3,
        Alignment:  []Test{cultural_fit.Teamwork, cultural_fit.LearningAgility},
        CoreTests:  []Test{CodeQualityTest, ProblemSolvingTest, DebuggingChallenge},
    }
}

the structure

treat your hiring like a monorepo:

hiring/
├── templates/
│   ├── cultural_fit/
│   │   ├── teamwork_test.go
│   │   └── learning_agility_test.go
│   └── technical_skills/
│       ├── code_quality_test.go
│       └── debugging_challenge.go
├── jobs/
│   ├── engineer/
│   │   └── software_engineer.go
│   ├── marketing/
│   │   └── digital_marketer.go
│   └── content/
│       └── content_writer.go
└── utils/
    └── benchmarks.go

benefits

this isn’t just structure
it’s clarity, transparency, evolution
tests replace vague feelings with measurable outcomes
reviews create accountability
history shows progress

the bottom line

want better hires?
start with better tests

test-driven development saved your code. now let it save your team.
