OpenText Principal Software Engineer interview questions

1. Round 1 : 2 simple java based programming questions. 2. Round 2: 1. Question about current project and architecture. 2. Few simple data structure related questions. 3. ROUND 3: With senior manager. 1. Questions on current project architecture, system design, some simple programming, some scenario based SQL queries etc. 3rd round progressed very well but they said you have wonderful logic development skills but you lack experience in designing. Very frustrating. Completely wasted two days. Don't go to them they have no respect for person time. They will call ppl for 2 3 rounds and simply give some stupid reasons for rejection.
