Being currently emloyed, I found a vacancy I was interested in. Using vacancy description data I found a person from appropriate department and then using company's database I found that person's contacts. I sended him my CV and received a replay in which he proposed me to arrange an interview. I was not asked to prepare something special, but I have prepared short form presentation on my experience. The interview by itself was quite informal, two managers have beeing representing the company. They were pretty surprised because of my presentation and they said that they are satisfied by my level. There was no any kind of tests at all, just explanation of my work and descussion of their work area. I had a possibility to watch an office, lab, work places and so on.
