Techatalyst interview questions

They took a First round of Interview over telephone in second week of December.Got Shortlisted ( as informed by HR ) and was conveyed next round of Interview would be scheduled in First week of January. Since then, their has been no way of Communication from HR. And suddenly when I tried to Contact, HR informed their has been no Vacancy even though I got a mail saying their has been vacancy through Social Group on the same day. Not a reliable Company at all. I am happy I didn't get placed in such Organization.
