Technical Coding System Design Behavioral
I interviewed at Qualys twice. First time was for a Lead Software Engineer role. I passed all the rounds, but they said I didn't have enough years of experience for the Lead position. The recruiter then suggested I apply for the Senior Software Engineer role. I went through all the rounds again and even provided my previous employment details when HR requested them to move forward with an offer. Now, they're saying it's a budget issue. During the second interview, the hiring manager asked a lot of questions about networking, which felt biased because the role wasn't specifically for someone with a networking background. Communication from the recruiter wasn't very clear.

Coding Technical System Design
So I interviewed for a Software Engineer position at Qualys. It started with a phone screen, then a technical coding round. After that, there were two more interviews where they tested my data structures, system design, and problem-solving skills. The team was really nice, and the questions felt fair. It was definitely tough but a good experience to show off my main software skills.

Coding Technical Behavioral Case
Applied through my college placement and went through a 3-round process. The first round was an Online Assessment on HackerRank which included coding, a Bash script task, and MCQs on CS fundamentals like OS, Data Structures, DBMS, SQL, OOPs, and languages like Java and Python. This round was easy and about 40 people qualified. The second round was a Technical Interview with questions on DSA (moving zeros, finding missing elements), SQL (JOINS), Linux commands, and CS concepts like the OSI Model, Interfaces, and Polymorphism. The interviewer was very happy with my performance and I advanced. 24 candidates moved to the next round. The third round was a mix of Technical and Managerial interviews. It involved more DSA (removing duplicates from arrays, both numbers and characters), HR/General questions (MS plans, parents' jobs, origin, math puzzles, handling team lead disagreements), and technical discussions about web apps and projects, including Chrome Dev Tools (Network/Application tabs). The interviewer was really positive, talking about me joining the company. Finally, after 11 days, 9 out of the 24 candidates were selected for the FTE role.
