Engineer Interview Questions

Engineers are responsible for designing and building products. In an interview context, expect to be quizzed on your technical skills, and also evaluated for your ability to work as a part of a team to get things built. The specific questions you are asked will depend on what type of engineering position you are looking for such as a specific engineering discipline like software engineer, electrical engineer, or mechanical engineer.

Top Engineer Interview Questions & How to Answer

Question 1

Question #1: What is the most challenging engineering project you've dealt with, and how did you ensure it was successful?

How to answer
How to answer: This question requires you to give a specific example. Ideally, you're able to choose a project that mirrors the type of work you'd do in the role you're interviewing for. Even if it's not your most challenging project, make sure you describe your obstacle(s) and the successful outcome clearly and enthusiastically.
Question 2

Question #2: In your current role, what steps do you take to avoid making mistakes?

How to answer
How to answer: Whether you have a formal process or not, list any specific measures you employ (i.e., digital tools, consulting with colleagues, etc.). Make sure your answer demonstrates a commitment to quality control, efficiency, and safety.
Question 3

Question #3: Describe a time you dealt with a difficult client or stakeholder.

How to answer
How to answer: This one also requires a specific example that demonstrates patience and good judgment. An employer is looking for evidence that you're able to confidently and calmly stand by your decisions. Share an example with a positive outcome.

Given two words as Strings, determine if they are isomorphic. Two words are called isomorphic if the letters in one word can be remapped to get the second word. Remapping a letter means replacing all occurrences of it with another letter while the ordering of the letters remains unchanged. No two letters may map to the same letter, but a letter may map to itself. * * Example: * given "foo", "app"; returns true * we can map 'f' -> 'a' and 'o' -> 'p' * * given "foo", "boa"; returns false * we can map 'f' -> 'b', 'o' -> 'o', we can't map 'o' -> 'a' * * given "bar", "foo"; returns false * we can't map both 'a' and 'r' to 'o' * * given "turtle", "tletur"; returns true * we can map 't' -> 't', 'u' -> 'l', 'r' -> 'e', 'l' -> 'u', 'e' ->'r' * * given "ab", "ca"; returns true * we can map 'a' -> 'c', 'b' -> 'a' */
