Cerner Interview Experience

Cerner arrived at our University for an Internship opportunity. They had only one criteria: Students must have GPA above 8.0.

The interview process had

Round 1(Hirevue Coding Test): Simple coding question, followed by problem faced by you during your project how you tackled it and all.

Round 2(Technical Interview): It started with introduction and the interviewer asked me:

• https://leetcode.com/problems/longest-common-prefix/. Gave the brute force. Interviewer asked me to optimize it further to which I first told him. I would Sort the array first, and then you can simply compare the first and last elements in the sorted array. The interviewer was pretty satisfied and asked me to the code the same. He didn’t asked me to run the code. Just asked me to dry run basically.
• He asked few question on software development cycle. I gave the bookish definition. He was genuinely a software developer so he asked me to forget the definition and asked how software development work in the real world.
• Again, He asked me to implement stack. https://www.geeksforgeeks.org/stack-data-structure-introduction-program/. Basically, he was more interested in the peak, pop, push and empty function. 
• He again asked some basic question on binary trees.
• Overall a great interview experience.
• It totally depends on your interviewer but I would suggest you to prepare basic DSA along with easy leetcode question also make sure you go through the problems that was asked to you in the HireVue Coding Round.

Round 3(Versant Test): Again, simple English test. You can clear it very easily.

Verdict: Selected
