Hey everyone, I applied through college for an internship opportunity at Juniper Networks, which can be converted to a full-time offer during your course of the internship.

Round 1 was on Hackerearth, and it included aptitude, technical, networking, and programming sections.

There were 4 programs, which I rate a 6 out of 10 in difficulty. Other sections were normal except for the networking section, which contained very application-based questions. I completed all 4 programming questions, as each was worth 50 marks. MCQs are worth 1 mark each.

Round 2 was a technical round with a panel of one interviewer. They asked me about my skills and how I could implement them in the networking field. They inquired about Manhattan Distance (Data Mining) and other C programs from Linked Lists and Trees. They ask for the concept and look for an efficient code.

Round 3 was a normal HR round in which they conducted a background check.

And then Juniper Networks confirms your internship.

Manhattan distance was the toughest question I have witnessed in the Juniper selection process.
