They approached me in a conference as they liked my talk and solution I offered and there can be an opportunity, then they did not respond to my Emails in a proper way. They send their representative to a summer school I attended later and told they are interested in the students' skills. I send the Email to the first contacts in the conference and CCed the second representative. They encouraged me to have a discussion. We had a nice discussion. They brought us to a dinner. They told they are going to invite me and my husband to Liechtenstein to stay to a hotel to see if we like the place and also I am going to have an interview with 3 people there. They did not get back to me. I send them Emails and they did not responded me properly again. The same happened to another friend in the summer school, she had two interviews over the phone but later they did not responded to her Emails that what is the final result. I am still wondering why they waisted my time and their time in the same place. If they are looking for future customers by increasing their visibility????!!!, definitely they lost at least two.
