I applied for a Software Engineer position at ServiceNow through a link the company shared after participating in a hackathon. I had three interview rounds and one online assessment round on the HackerRank platform.
The first round consisted of two Data Structures and Algorithms (DSA) questions: a. Graph - Find if an array of strings can be chained to form a circle. b. An easy-medium array problem The interviewer also asked about my project and database management system fundamentals.
The second round focused on DSA and problem-solving. The interviewer asked me about my project in detail, including some DB management questions. I answered all the questions until the Dynamic Programming problem - Rotate Function, which I could not answer correctly.
I did not clear the third round.
