FAQ for Trainees

Why should I apply to Castrén & Snellman?

We offer versatile career options and interesting tasks for experts and trainees from different fields. As a Castrén & Snellman trainee, you can be exactly who you are. You will become a part of a community that shares a joy of getting things done and a genuine interest towards business law. We work in an energetic, fast-paced and cheerful atmosphere, and the enthusiasm we have towards our work and each other is palpable.

Other good reasons to apply to C&S are the opportunities we offer to develop your expertise, the freedom to work remotely, great benefits and an inviting office.

 

What are you looking for in a trainee?

The most important thing for any C&S employee is the spark – we give our everything for our clients and our team. This spark is made possible by skilled and diverse individuals, mutual trust, and sincere and direct interaction. Being always ready and willing to help each other out is something we appreciate. Most of all, we value whatever it is that you can bring to our work community as yourself.

I am applying to your law student trainee programme. What is the process like?

First, submit the application form along with an application letter, your CV and a transcript of your studies. After that, reply to the video interview question we send you. Based on the applications and the video replies, we will invite some applicants to group assignments and individual interviews, aka to recruiting days. We will select the most suitable candidates shortly after the recruiting days and will let all attendees know the results over the phone.

 

I have been invited to attend a recruiting day. How should I prepare for the group assignment?

There is no need to stress about the group assignment that might be a part of the recruiting process of the position you are applying for. Everyone takes part in the same assignment, and it is not something you can prepare for. Just come to the recruiting day as yourself. Try to be well rested though, as this enables you to present yourself in the best possible manner.

 

What benefits do you offer to trainees?

Our trainees receive a lunch benefit, a sports and culture benefit and occupational health services.

In addition to friendly and smart colleagues, we also offer fun employee events and a functional and inviting office that includes Tori, our meeting spot, and Paja, our own gym. You can grab breakfast at Tori in the morning and swing by for a snack in the afternoon.

We value everyone’s efforts and enthusiasm in bringing their skills to the table when we provide our full-service offering to our clients. We encourage continuous learning, support it by offering training, and develop as a community by supporting one another.

 

Are the trainee positions paid?

All of our trainee programmes are paid. We actively monitor the pay recommendations by trade unions and associations, and it is very important to us that our trainees receive just compensation for their traineeship.

 

Can I work remotely?

Yes, you can! Our remote working policy is very flexible. The main rule is that each team decides on the best ways of working and communicating for them.

An exception to this is junior trainees, trainee assistants and our reception employees, who, due to the nature of their work, have to work at the office.

 

I am planning to apply in the next round of traineeships. When does the application period begin?

We are very happy to hear that you are interested in us! We announce the beginning of each application period on our Careers page and in Instagram, so make sure to follow us here

In addition, we announce the application periods for trainees first in our C&S Student Newsletter. You can subscribe to the newsletter at any time here.

We delivered two information design workshops for the legal department of the Finnish Centre for Pensions, with participants from both legal and other professional backgrounds. In the sessions, we applied the principles of legal design thinking to the Finnish Centre for Pensions’ field of operation and background materials, also utilising AI as a design tool. The participants found the tailored training highly useful and commended the trainers for their in-depth familiarisation with the Centre’s opinion drafting process and operating environment. As a result of the workshops, our experts proposed a new structural and linguistic model for the legal department of the Finnish Centre for Pensions for drafting opinions and guidelines. The proposal was well received as clear and applicable to the participants’ everyday work. In addition, we presented tailored AI use cases to support experts, allowing for a more efficient AI-assisted way of working. Our experts who delivered the workshops combined their legal expertise with their leading experience in legal design. The participants appreciated this versatile expertise, which enabled a knowledgeable, creative and applied approach to legal writing. ‘C&S created a well-structured training tailored to our needs, providing clear direction for our organisation and concrete takeaways for our experts in their day-to-day work,’ says Mari Kuunvalo, Head Of the Legal Department at the Finnish Centre for Pensions.

We advised Aktia Bank Plc on the issuance of an EUR 80 million Additional Tier 1 (AT1) bond. The bond pays a fixed interest rate of 6.75 per cent semi-annually. The bond is perpetual, and Aktia has the right to redeem or repurchase it in accordance with the terms of the bond, subject to certain conditions. The bond was issued on 1 April 2026. In addition, we assisted Aktia in listing the bond on the Nasdaq Helsinki Ltd stock exchange. For the listing, we prepared Finland’s first EU Follow-on prospectus for a bond. The EU Follow-on prospectus was introduced on 5 March 2026 with an update to the Prospectus Regulation (EU) No. 2017/1129. The EU Follow-on prospectus is a new type of prospectus that can be used, among others, by issuers whose securities have been admitted to trading on a regulated market continuously for at least the 18 months preceding the offer to the public or the admission to trading on a regulated market of the new securities. A follow-on prospectus is simpler than a so-called traditional prospectus, and it is intended to avoid repeating information that the issuer has already disclosed. Nordea Bank Abp acts as the sole structuring advisor for the issue of the Notes. Nordea Bank Abp, Danske Bank A/S and ABN Amro Bank N.V. act as the lead managers for the issue of the Notes.
