I went through the translated version of your landing page and here’s the feedback:
Main Heading - Its too long, Keep it a single line, simple and powerful. E.g. “Seeking Sales Champs” or “Now Hiring! - Sales Consultants” etc.
Main Picture (Hero Shot) - Change the image to a more professional looking image, maybe a female wearing formal suit, spectacles.
Features - Change the “Plus” symbol to simple bullets, or you can get some icons from https://flaticon.com and use them. E.g. you can use a dollar or money icon for “Well paid for every sale you make”, and so on.
Call To Action (CTA) - Keep it simple, you can change it to “Apply Now!”.
First Testimonial (Marie) - Move it to the main header (blue), so it looks like it belongs.
Testimonial Section - Add a heading to this section. Something like - “Here’s what our employees think about us”.
Footer Section - Add a quick contact form in this section. Visitor’s are more interested in filling up a small form that getting on a call. Also move the names “Jacob” and “Aleksander” to the same section (grey).
