Quest Software interview questions

Gone through three stages of the interview, all went well, expect for some stuff at stage 3 in which one of the guy keep trying to make me look like i know nothing, but the other dude is really cool. he kept asking bout my current company and what kind of software, hardware and clients we are engaging in and when i decided to not disclose it, hence the little bickering bit. long story short, didnt get the job, they told me they found someone for the position but i went to check on the job portal, the posted the vacancy 1 day ago, so i dont really know if there is a vacancy or are they surveying the market

three rounds total، two technical one hr، its went fine Informatica interview for first round and manager round for second round, HR round for third round, and first round went with difficult questions
