ikaSystems interview questions

I received 3-4 emails from the recruiter over several weeks asking for my availability. I did not receive any response till the last one. Phone interviews went well and was called for interview. It went well but they did disclose that all the roles would be high pressure and work require working close to 60 hours a week. It was really honest of them to disclose this. I emailed HR after interview for feedback, no response. It would have been at-least nice to have know via email if was not considered for the role, given the time and effort.
