Working Student Application: Templates, Tips, and Common Mistakes

You are studying and looking for a working student position? Working student roles are the best way to gain practical experience alongside your studies while earning money. But competition is fierce: popular working student positions at companies like BMW, Bosch, or SAP often attract over 100 applicants. In this article, we show you how to apply successfully, what mistakes to avoid, and what your cover letter and resume should look like.

What Makes a Working Student Application Special?

Unlike full-time positions, as a working student you cannot yet impress with years of professional experience. Instead, other factors take center stage:

• Relevance of your degree: Does your field of study match the position?
• Practical experience: Internships, projects, volunteer work
• Motivation: Why this specific company, this department?
• Availability: How many hours per week, time period, semester breaks

Recruiters know that working students have less experience. They are looking for potential, willingness to learn, and cultural fit. Your cover letter must convey these points.

The Working Student Resume

As a working student, a one-page resume is perfectly sufficient. Structure it as follows:

1. Personal data and contact information
2. Education: Your degree program comes first because it is your primary occupation. Include university, program, specializations, current GPA (if strong), and expected graduation date.
3. Practical experience: Internships, part-time jobs, working student positions, research assistant roles. Here too: results over task lists.
4. Projects and engagement: University projects, hackathons, student organizations, volunteer work.
5. Skills: Programming languages, software, languages, certifications.

Example: Work Experience in a Working Student CV

Here is what an entry in your resume could look like:

Online Marketing Intern | StartupXYZ GmbH, Munich
Sep 2025 — Feb 2026

• Managed Google Ads campaigns with a monthly budget of EUR 5,000 and reduced cost-per-lead by 22%
• Created and executed content calendar for Instagram and LinkedIn (8 posts/week)
• Conducted A/B tests for landing pages, improving conversion rate from 2.1% to 3.8%

Note: even as a student, you can work with numbers and results. A university project can be formulated just as impressively as professional experience.

The Working Student Cover Letter

Your cover letter should not exceed one page. Structure it as follows:

Opening: Grab Attention

Even as a student, you can craft a strong opening. Here are three approaches:

• Through a project: "In my semester project, I developed a machine learning model for customer segmentation — exactly the type of work that excites me about your working student position in the data science team."
• Through the company: "Since I started following your open-source project on GitHub, I have been fascinated by your approach to sustainable software development. As a computer science student focused on Green Computing, I want to join your team."
• Through a referral: "Your working student Anna Schmidt told me about the open position at the university career fair — her enthusiasm for the team was contagious."

Body: Relevance and Motivation

Connect your studies with the position. Show which courses, projects, or internships have prepared you for this role. Be specific:

"In my 'Databases and Information Systems' module, I designed a relational database model for a fictional online shop and implemented it in PostgreSQL. I want to deepen this experience in your working student position on the backend team and apply it to production systems."

Also explain your motivation: Why this company? What excites you about the department or product? Recruiters immediately notice whether you have genuinely engaged with the company.

Closing: Availability and Call to Action

State your availability clearly:

• Weekly hours: "I am available 20 hours per week, and more during semester breaks."
• Start date: "I can start immediately from April 1, 2026."
• Duration: "Ideally for at least 12 months."

The 5 Most Common Mistakes in Working Student Applications

Mistake 1: Generic Cover Letter

"I am applying because you are a renowned company." This could apply to any company and shows zero research. Name specific products, projects, or company values.

Mistake 2: Listing Irrelevant Part-Time Jobs Prominently

Your waiting job shows work ethic but should not be the first entry on your CV when applying for a tech working student position. Prioritize relevant experience. If you have none, frame transferable skills: "3 years in hospitality: stress resilience, customer orientation, teamwork under pressure."

Mistake 3: Missing ATS Optimization

Even working student positions at large companies are filtered through ATS systems. Use the keywords from the job posting. Read our article on improving your ATS score.

Mistake 4: No References or Recommendations

If you have a professor or former employer who would recommend you, mention it. "Professor Dr. Mueller (Chair of Computer Science, TU Munich) is available as a reference." This sets you apart from other applicants.

Mistake 5: Missing or Unrealistic Salary Expectations

Typical working student hourly rates in Germany range from EUR 13 to 20, depending on industry and qualifications. In IT and consulting, EUR 18-22 is not uncommon. Research typical rates in advance on our salary comparison.

Where to Find Working Student Positions

The best platforms for working student positions in Germany:

• LinkedIn: Filter by "working student" and your location
• Indeed: Large selection, including smaller companies
• StepStone: Primarily large employers
• University job board: Often exclusive positions only for students at your university
• Career fairs: Direct contact with recruiters, often faster application process

Summary

A successful working student application convinces through relevance, specificity, and honest motivation. Use your studies, projects, and even part-time jobs as a springboard. Tailor each application individually and do not forget ATS optimization.
