Rockall Technologies interview questions

The interview consists of 5 rounds, through which I made it till 2nd round. Where 1st round being HR call to enquire your career background and check your communication skills, 2nd round will be technical round by a Sr. SRE who checks your basic knowledge of Linux, Webservices, AWS, Architecture, troubleshooting, etc. 3rd round written report test on a problem scenario, 4th round is again technical round, 5th will be final managers round.

- Two initial calls with recruiter and then hiring manager - Technical test writing Python to query an API, Bash to check for valid emails and building a SQL query - 3 hour interview with HR, management and engineering team Waited 2 weeks to get results of technical test and then another 3 weeks to hear back regarding the final interview Received a cut and pasted reply "we have decided not to proceed with your application" Considering over 5 hours of interview time plus a weekend of writing code and building a database server it was frustrating to receive such a curt reply.
