Graduate software engineer Interview Questions

One was challenging and the other was easier.

When did they get back to you?

It took about 1 1/2 weeks after I submitted the coding sample, I got an email from a recruiter letting me know I would not be moving forward.

There's quite an extended back and forth in actual interviews for questions like this, so nothing quite like real practice. The Prepfully ThoughtWorks Graduate Software Developer experts have actually worked in this role, so they're able to do an honest-to-God accurate mock, which really puts you through the paces. prepfully.com/practice-interviews

public static String returnString(TreeNode node) { if(node == null) { return ""; } if(node.left == null && node.right == null) { return node.data; } String leftData = returnString(node.left); String rightData = returnString(node.right); return (root.data + leftData + rightData); }

There's a lot of elements to typically cover in these questions, clarifications, scoping, making sure you're answering the actual question the interviewer is looking for you to answer, etc. Could be worth doing a mock interview with one of the Prepfully Bloomberg Graduate Software Engineer experts... they've worked in the role so they clearly know how to get through the interview. prepfully.com/practice-interviews
