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.

1st question : 210 points. Write a program to simulate a keyboard with given keys and their operation. You need to print the final text to STDOUT. Type of Keys: Each key affects the movement of the cursor on editor. The cursor position is identified by row and column. alpha numeric space => this key inserts their respective symbol at cursors position and shift cursor. @ => [CAPS Lock] toggles caps lock, i.e., if CapsLock is 'ON' after this key press it will be 'OFF' and vice versa. Initially CAPS Lock in 'OFF'. # => [ENTER/New Line] inserts a new line character at cursor position and shift cursor position. < => [LEFT arrow] moves cursor to one step left (if available). If cursor is at the starting of the row, it moves to end of the row above (if available). > => [RIGHT arrow] moves cursor to one step right (if available). If cursor is at a row end it moves to starting of the row below (if available). / => [Backspace] deletes one character from the left of the cursor and move cursor one step left. It follows same direction rules as LEFT arrow key (<). ? => [Down arrow] If cursor is on last row nothing changes. The cursor moves to original column in next row if there are not enough characters in next row, cursor shifts to the end of the new row. Note: If key is pressed continuosly original column will not change with every key press. ^ => [UP arrow] If cursor is on first row nothing changes. The cursor moves to the original column (current) of the previous row, if there are not enough characters in previous row cursor shifts to the end of the previous row. Note: If key is pressed continuosly original column will not change with every key press. Example: Input: asdf#q#pqr^^23 Output: asd23f q pqr Input: One line of input characters (as defined above). Output: The formatted text. Example 1: Input asdf1# @qwe^23 Output asdf231 QWE Example 2: Input asdf1#@ qwe<<<//23 Output asdf123QWE Explanation: asdf1 prints asdf1 asdf1 # inserts new line character after asdf1 @ qwe switches caps lock from off to on and inserts QWE asdf1 QWE <<< shifts cursor position 3 position left // deletes 2 character (space and new line) from left of Q character asdf1QWE 23 inserts 23 from current cursor position asdf123QWE
