Internship in Spain: The 3-3-3 Rule for Your First Weeks

TL;DR

TL;DR — In your first weeks, use the 3-3-3 rule: three routines to lock in the first three days, three people to meet the first three weeks, three habits to build the first three months. Do this and month four takes care of itself.

Every intern's first month follows the same rhythm: chaos, adjustment, then flow. The 3-3-3 rule shortcuts the middle stage.

The framework

First 3 days — 3 routines to lock in

1. Sleep schedule
   • Non-negotiable: same wake time weekdays + Sunday
   • Fixes: jet lag, mood, ability to eat at Spanish times
2. Morning walking route
   • Same 20-minute walk before work every day
   • Fixes: orientation, discovery of your local café, coffee-shop familiarity
3. Evening wind-down
   • Phone away 30 minutes before bed, one glass of water on the nightstand
   • Fixes: adjustment insomnia

First 3 weeks — 3 people to meet

1. Your work mentor — beyond the introductory coffee. Book a real 1:1 in week two.
2. A local (not another intern) — through a Meetup, language exchange, gym, choir, or church.
3. A more senior intern or recent graduate — for tribal knowledge about your placement or city.

Skip this and you'll be homesick by week five.

First 3 months — 3 habits to build

1. One deep-work block daily
   • 90 minutes of undistracted work on your hardest task
   • The one thing that separates good interns from great ones
2. Weekly Spanish milestone
   • See our language skills guide for month-by-month milestones
3. Fortnightly feedback conversation
   • Ask your manager: keep / stop / start
   • The single fastest way to compound at work

Why this works

Most intern struggles come from either:

• Under-structure — freestyling three months and drifting
• Over-planning — burning out on a rigid plan by week two

3-3-3 is opinionated but light. It gives you a scaffold without a schedule.

Days-1-through-3 checklist

• Buy a Spanish SIM
• Set your wake time
• Walk your commute at least twice
• Find your local café + supermarket
• Register empadronamiento (if not already)
• Introduce yourself to at least one flatmate

Weeks-1-through-3 checklist

• Complete workplace onboarding
• Book 30 min with your mentor
• Attend one Meetup / social event
• Message one alumnus of your programme
• Join one gym / class / group
• Do the paperwork rounds (TIE, health, bank)

Months-1-through-3 checklist

• Ship one visible project by end of month 1
• Give one presentation in Spanish by end of month 3
• Complete one weekend trip per month
• Save one work sample per week for your portfolio
• Ask for feedback at month 1, 2, 3

The weekend rule

Weekends are for exploration and rest — not catch-up work. If you can't finish work in a Mon–Fri week, adjust the plan, not the weekend.

What to skip

• Don't try to become fluent in three months. That's a 12–18 month arc.
• Don't spend every night with other interns speaking English.
• Don't sleep in until noon on weekends. Kills the Spanish evening pattern.
• Don't take on side projects until month 3. You need bandwidth for arrival.

Key takeaways

1. Structure the first three days, three weeks and three months separately.
2. Meet a local — not just other interns.
3. Deep-work daily + weekly language + fortnightly feedback = compounding.
4. Weekends are for recovery + exploration, not catch-up.

FAQ

What if I fall off the routines by week two? Restart Monday. Nobody keeps a routine every single day. Consistency across weeks matters, not perfection within one.

What if my manager is absent? Escalate to your placement coordinator in week 3. A missing manager is a placement risk, not a personal problem.

Should I go home for a weekend early on? Push it past week 6. Early home visits often reset your adjustment clock and delay integration.
