title: Cheatsheet (Interviewer)
|
||||||
|
---
|
||||||
|
|
||||||
|
This is a straight-to-the-point, distilled list of technical interview Do's and Don'ts **for interviewers**, mainly for algorithmic interviews. Some of these may apply to only phone screens or whiteboard interviews, but most will apply to both. I revise this list before each of my interviews as an interviewer to remind myself of them and eventually internalized all of them to the point I do not have to rely on it anymore.

||||||

|
||||||
|
**If you are a candidate you probably do not need to know this section well. You may read this to get a better sense of what an interviewer is supposed to do during an interview.**

### Before interview
|
||||||
|
|
||||||
|
| | Things |
|
||||||
|
| --- | --- |
|
||||||
|
| ✅ | Make sure your surroundings are well-lit. |
|
||||||
|
| ✅ | Find a quiet environment with good Internet connection. |
|
||||||
|
| ✅ | Ensure webcam and audio are working. Test that your VC app is working well. |
|
||||||
|
| ✅ | Prepare two to three questions and be familiar with the different approaches for solving the questions. |
|
||||||
|
| ✅ | Familiarize yourself with the coding environment (CoderPad/CodePen). Set up the coding shortcuts, turn on autocompletion, tab spacing, etc. |
|
||||||
|
|
||||||
|
### Introduction
|
||||||
|
|
||||||
|
| | Things |
|
||||||
|
| --- | --- |
|
||||||
|
| ✅ | Check if candidate wants to use the restroom or take a break. |
|
||||||
|
| ✅ | Give an overview of the interview format (introduction, duration, programming languages available, 5 min at the end for Q&A). |
|
||||||
|
| ✅ | Do a self-introduction and get the candidate to introduce themselves. |
|
||||||
|
| ✅ | Explain to candidate that they do not have to finish all questions and you might interrupt them abruptly. |
|
||||||
|
| ❌ | Allow the candidate to spend too long introducing themselves. |
|
||||||
|
|
||||||
|
### Upon delivering the question
|
||||||
|
|
||||||
|
| | Things |
|
||||||
|
| --- | --- |
|
||||||
|
| ✅ | Ask if the candidate has seen the question before. |
|
||||||
|
| ✅ | Give a small example for the question and the desired output. |
|
||||||
|
| ✅ | Get the candidate to talk through the solution first before diving into coding. |
|
||||||
|
| ✅ | Provide hints where appropriate. |
|
||||||
|
| ✅ | If candidate is still stuck after providing hints, provide the solution and move to coding so that you can get coding signals. |
|
||||||
|
|
||||||
|
### During coding
|
||||||
|
|
||||||
|
| | Things |
|
||||||
|
| --- | --- |
|
||||||
|
| ✅ | If whiteboard interview, stand alongside candidate but also giving them space, instead of being distant, e.g seated down. |
|
||||||
|
| ✅ | Take note of all the positive and negative signals. |
|
||||||
|
| ❌ | Check the time in an overly-obvious manner. |
|
||||||
|
|
||||||
|
### After coding
|
||||||
|
|
||||||
|
| | Things |
|
||||||
|
| --- | --- |
|
||||||
|
| ✅ | Ask for candidate to provide test cases and run through the code with them. |
|
||||||
|
| ✅ | Point out edge cases candidate missed and ask the candidate to address them. |
|
||||||
|
| ✅ | Ask for time complexity and space analysis. |
|
||||||
|
| ✅ | Preserve the code somewhere - take a picture or copy the code out. |
|
||||||
|
| ✅ | Stop the candidate when there is 5 minutes left. e.g. ("I'll stop you here and let's go to the next section") |
|
||||||
|
|
||||||
|
### Wrap up
|
||||||
|
|
||||||
|
| | Things |
|
||||||
|
| --- | --- |
|
||||||
|
| ✅ | Allow candidate to ask questions and answer them to the best of your ability. |
|
||||||
|
| ✅ | Thank the candidate and wish them all the best. |
|
||||||
|
