Prison and a change of life

Matej would probably still work in the field of recruitment, leading interviews and consulting employers, if Iranian security police didn’t arrest him in Tehran on 23rd August 2012, while he was working on one of his recruitment projects in the country.

Iranian authorities accused Matej of  spying for the CIA. He spent six months in notorious Evin Prison, facing harsh conditions of solitary confinement and a possibility of a death sentence.

Iranians eventually released him in February 2013, but after what had happened to him in Iran, he could not return to recruitment anymore. The story of New Generation Recruitment ends, but Interview Penguin lives on.


Growing in traffic and popularity

During the next twelve months, Matej focused on building, and he also started more than a dozen other, smaller specialized websites in the field of career advice, cooperating with recruiters and interview coaches that specialized in the respective fields.

He invited and paid guest authors to write articles for, to help him with an advice for job seekers in the fields he had no experience with (mostly interview questions and answers for various IT and healthcare positions).


Experiments & statistics

Matej tried various white hat and black hat SEO techniques to improve the position of Interview Penguin in the search results of Google, in the years of 2013 and 2014. The action led to both increases and decreases of traffic to the website, until he finally decided to stop doing SEO. Since then he has been focusing only on building quality content that can deliver real value to the visitors, and to promoting the website in a natural way.

The website has been enjoying a relatively steady flow of traffic ever since.
