In Finland, open applications are quite common. Sending open applications is of course a way to maybe get an interview, but it is also an efficient way to get acquainted with the market.
To make an open application, you need to study the industry and the company you’re applying to, get informed about the current state of business and read the news about the field. Developing a network is an important part of sending efficient open application, since that’s how you will most probably get to hear about good opportunities or good timings to send your resume and cover letter. Discussing with your networks is also very important if you want to better understand the kind of skills needed for a certain position or company, as well as their current challenges.
It usually works better to send an open application to someone you have already met, or to a company you’ve already been in contact with somehow.
Open applications work the same way in Finland as in other countries. You can send an email to get a confirmation that they’ve received your resume about a week after having sent the first one. Calling is always a bit sensitive in Finland, unless you already know the person or have at least already met somehow.
Open applications can also be a bit unformal, at least for a first contact. LinkedIn is a very good tool to let people know that you are interested in their company or product.
An open application should contain who you are, what you are able to do, how this skill set relates to the company challenges or needs and why they should consider you. This can be done in a very concise and clear way, in an email, a cover letter and a resume.
