The interviewer was excellent and professional, making the experience comfortable. The interview had medium difficulty, and he was well prepared, clearly familiar with my profile and interested in learning more.

Easy to difficult, with coding being very hard. Focused mainly on DSA and design principles, followed up by dealing with real-time situations. Build-up is demonstrated, not a black hole, by data points where the 'h' data point is denoted 77-97e.

Phone screen by interview: questions were on networking, Linux, web, etc. They were not very difficult, but I was quite rusty at the time, which was foolish because I thought it was a dream job. I haven't interviewed again since.
