At Cisco, the interview process begins with an initial resume screening, where recruiters assess the applicant’s skills and experience relative to the job opening. This step is usually followed by an Online Assessment (OA), which tests coding skills and logical reasoning.
After successful completion of the OA, candidates usually face one or two phone screens. These sessions focus on technical questions, potentially some cultural fit questions, and are followed by an onsite round. The onsite typically consists of multiple interviews that cover coding, system design, and sometimes a review of past projects or experiences. Overall, the difficulty level is considered to be challenging but fair, aiming to identify candidates who are both technically proficient and a good match for Cisco's culture.
Cisco initially screens resumes focusing on relevant experience and technical skills. Additionally, candidates might undergo one or more online assessments evaluating coding proficiency and problem-solving ability.
After passing the resume check, applicants typically face a preliminary screening call. This involves basic technical questions and discussions about past projects and experiences, used to gauge fit and communication skills.
At Cisco, the interview process typically begins with one or two phone screens. These initial calls focus on assessing your technical knowledge and problem-solving skills through coding questions and discussions about your past projects and experiences.
The phone screen(s) not only gauge your technical acumen but also test your communication skills and fit for Cisco's collaborative culture. It’s a crucial step to advance to the more in-depth onsite technical interviews.
At Cisco, onsite interviews typically include four to five rounds focusing on a mix of behavioral questions, system design, and live coding challenges. The day is structured to assess both technical prowess and cultural fit within the team.
Each session during the onsite visit is meticulously planned. Candidates will face one or two behavioral interviews, one system design interview, and two coding interviews, often with a focus on real-world programming scenarios and problem-solving skills.
After the interview rounds at Cisco, candidates may undergo team matching to ensure a good fit with specific project needs. This is followed by offer negotiations before finalizing employment details. Meetings with executives are uncommon.
Cisco's interview is very similar to the typical coding interview but has a slight tendency to shift towards easier and classical Dynamic Programming, Two Pointers, and Backtracking, and not so much in Graph Theory and BFS/DFS traversals. At Cisco, the coding interview challenges generally linger around a medium difficulty, not quite on the level of other tech giants at FAANG.
