Why a job simulation

Learn by doing the job, not by reading about it

  • Try the job before you applySpend a working week in a role and see whether you like the work.
  • Real project documentsDrawings, procedures, work orders and specifications, written the way a working team writes them.
  • Every ticket markedYou get feedback on each hand-in and a model answer when you finish it.
  • Colleagues you can askAI colleagues, clearly labelled. They explain and point you to the right document; they do not hand out answers.
  • Work to talk aboutA set of finished pieces of work you can describe at an interview.
  • Proof you can verifyAn optional certificate with a public verification page, and an entry on your profile marked as a job simulation.
  • Free to startDays 1 to 5 are free. No card to start.

How it works

Five steps, one working week

About 10 hours of tickets in the free edition, self-paced across five working days. A day opens when you hand in the previous day's tickets.

  1. Step 1

    Start free

    Create a free account, pick a role and start. Days 1 to 5 are free, and no card is needed.

  2. Step 2

    Morning email and tickets

    Each working day your lead sends an email and assigns tickets, as on a real project.

  3. Step 3

    Documents and hand-ins

    Read the specifications and drawings, then hand in your work. Hands-on tasks are finished in EDWartens Lab and uploaded as a FAT sheet.

  4. Step 4

    Checked work and model answers

    Every task is checked as you hand it in. You see the model answer and why.

  5. Step 5

    Certificate, if you want one

    A graded, verifiable certificate is optional: £14.99, VAT included.

Free, Certificate, Premium

A day in a simulation

Start the day with an email and a ticket

This is a real morning email and a real ticket from the PLC Programmer job simulation. Every role works this way.

Morning email · company

Welcome to Tarnbrook Controls, line BFL-200

From: Project Manager, Tarnbrook Controls Ltd (simulated company)

Welcome to the team. You are the junior PLC programmer on project BFL-200, the control upgrade of bottling line 2 for Larkfield Drinks. The Lead Engineer owns the software and you report to them.

How we work here: tickets have a number (BFL-101 and up) and acceptance criteria. Documents carry a number and a revision letter and we never overwrite an old revision. At the end of each day send a three-line status: done, doing next, blocked. Questions to the client go through the query log, not by phone.

Site rules and our project standards are on one page in the attachment. Read it before anything else.

BFL-101 Ticket · about 45 min

Site induction and project standards

Raised by: Client Safety Officer

Before anyone from Tarnbrook Controls touches line 2, the client's Safety Officer wants proof that you have read the site rules and understand the standards the project follows. The questions come from the one-page site rules and standards sheet (BFL200-HSE-001). Take your time: on a real site a wrong answer here is a wrong action later.

Acceptance

  • At least 60 percent correct.
  • You can say why each right answer is right.

Job simulation, virtual work experience or a placement?

The three get mixed up. They are different things, and all three have a place. Here is how they differ.

Written for the UK

UK settings and the standards you will hear about

The simulated companies are UK-style employers, the money is in pounds, and the work names the standards a UK engineer meets: for example BS 7671, IEC 61131-3, PUWER 1998, CDM 2015, DSEAR and ATEX, IEC 62443 and ENA G98 and G99, depending on the role.

  • Each role page lists the UK standards and regulations for that role, for awareness. The tasks use simplified data, so always read the current edition of anything you rely on.
  • Schemes such as the ECS card and CompEx are described so you know they exist. A job simulation does not lead to them.
  • UK pay appears only where we can give a dated, sourced figure. Otherwise we leave it out.
  • The certificate is issued by WARTENS LTD. It is not an accredited or regulated qualification.

Questions

Quick answers

All the questions

Is the data real?
No. The data is made for the simulation so that it looks like real business data, with the same problems, and so that nobody's private data is used.
Do I need to install Python or a notebook?
No. Where a real analyst would use Python or SQL, the role page names it and says what you use here instead; a spreadsheet is enough for every calculation.
What is a job simulation?
A job simulation is a realistic training project at a simulated company. You get the emails, tickets and project documents a junior engineer gets, do the work in your browser, and have every task checked. Hands-on tickets are finished in EDWartens Lab and uploaded. It is not a real job, and it is free to start.
Is a job simulation a real job, an internship or work experience?
No. It is a training project at a simulated company. It is not employment, an internship, a work placement or a job offer, and no employer is involved.
Is it really free to start?
Yes. Days 1 to 5 are free: the tickets, the documents, checking and model answers. The certificate (£14.99) and Premium (£53.99) are optional. Both prices include VAT.
How many hours is it?
The free edition is days 1 to 5, self-paced, and each role page lists its tickets with minutes. The hours on your record are active hours you spent on EDWartens, not hours at a company.
What do I get at the end?
A record of your work with your scores by task and skill, and the dates. The optional certificate adds a graded score, a verification page and a QR code.

Honest limits

A job simulation is a realistic training project at a simulated company. It is not employment, an internship or a work placement, and it is not a job offer. Hours are active hours the learner logged on EDWartens UK.
