ServiceNow Software Development Engineer interview questions

Round 1 - online coding with their software developer. We solved 2 coding questions and then he asked me number of questions on Java, SQL. Round 2 - onsite 3 hour interview consisting of 4 rounds, 3 were white board coding rounds and last was manager talk. Everything went well, they said they'll provide feedback in next 2 days, when no response was received I asked for the same. They did not even care to reply by email and just sent an automated rejection email (from do-not-reply) which is generally sent when you submit online application for resume selection. Very disappointing. They should at least provide personalised feedback (even one liner) and not an auto-generated email.
