3rd Sense interview questions

I contacted the company via email and I was invited to visit the offices for an interview. I was interviewed and they told me they would decide in the next 2-3 weeks. Emailed them after 3 weeks, no response was offered. 4 months later they contacted me, to communicate that they did fill in the position, however, they had another position that could fit my profile. I was invited for a second interview. I went to the second interview and I was informed they would take a decision the following week. No response was given. Emailed them to follow up and none ever replied.
