was founded in April 2011, by recruitment consultant Matej Valuch (Matej uses an English pen name Matthew Chulaw on the website).

Matej ran a smaller recruitment consultancy called New Generation Recruitment, established back in 2008 in Slovakia.  IRBIS, IBM, Orange Employment, Siemens, O’Donnel Griffin belonged to his clients, together with other smaller companies from different parts of the world.

While interviewing job candidates, and consulting corporate managers, Matej realized that most people, from both the ranks of employers and job seekers, were poorly prepared for the interviews.

He decided to start a website, trying to share his expertise, and help job seekers to understand what matters in an interview, and how to get a job. was founded, and Matej wrote first twenty articles for the website, while continuing to focus mostly on his career in recruitment consulting & interviewing candidates for his clients.

Prison and a change of life

Matej would probably still work in the field of international 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 his work 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, either alone, or cooperating with recruiters and interview coaches who 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 specializations). One of the authors, Glen Hughins (a pen name), has been a major contributor to the website, with over 30 articles in the field of teaching & education administration interviews, which belong to the most popular and shared articles on Interview Penguin.


Experiments, statistics, growth

Matej tried various SEO techniques to improve the position of Interview Penguin in the search results of Google, in 2013 and 2014. The experiments 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 which delivers excellent value to the visitors, and promotes the website in a natural way only. The website has been enjoying a relatively steady growth of traffic ever since.

In 2019 & 2020 the website has undergone a major transformation, with hundreds of new articles being published, and all old content updated to meet the highest standards. Yet our goal has remained the same: To help the job seekers to succeed in their interviews and their career, with a professional yet simple to understand advice. This sets us apart from other players in the field, or at least it is something we aspire to achieve.
