Lumen Technologies Interview Questions, Process, and Tips

Round: Resume Shortlist
Experience: I had a standard resume for this company as per our institute placement cell norms. I kept changing the “areas of interest” depending on the company and the profile offered.

Round: Test
Experience: First round was based on aptitude and coding based questions. The questions on programming were related to linked lists, data structures, pointers and sorting. The questions on aptitude were related to Permutation and Combination among others. 50-60 students had applied out of which 15 were selected for technical interview.

Round: Interview
Experience: In the technical interview my area of interest was asked. I went with data structure. Then they asked all sorts of questions in data structure ranging across linked list, trees, sorting, searching, doubly linked lists. They asked me a puzzle based on buoyancy. If a brick is thrown out of the boat in the water then what happens to the level of water. Technical questions on practical applications of linked lists, networking etc were asked. I was also asked about the technicalities of common apps that are used by the people.
Tips: Prepare for data structures in depth to perform well in the interviews.
