Are you afraid of the code interviews?😱😱😱
You're not alone!🫂

I've done many on both sides (candidate and interviewer)!

Here are some tips that helped me succeed:

[1.5 minutes]

1/10🧵

During the interview you are being evaluated in many aspects and not only your coding skills

So while solving the technical questions, talk to the interviewer and explain what you are trying to achieve.

Communication is an important skill!

2/10🧵

Some people get anxious during the interview and might get blocked or forget even the basics. This is a very common problem

To overcome this what I did was:
• Practice
• Practice
• Practice!

I solved many many problems on the white board before going for an interview

3/10🧵

Still on practicing, ask a friend to do a mock interview with you.

This is a great opportunity to understand how you feel when being interviewed and you can start to overcome your fear

Do these a couple of times until you feel confident!

4/10🧵

Study:
• Data structures
• Data structures
• Common algorithms (sort, search, recursion)
• Specifics or your area: Web, Mobile, ML, …

Nice to have:
• Analysis of Algorithms (big O notation)
• Graph theory

5/10🧵

The interviewer is not there to trick you. They are there to help you.

Ask questions!

If you didn't understand the problem, ask for clarification!

Ask about the input, problem assumptions, discuss corner cases

6/10🧵

Before starting to code, if possible, create your own set of input data. Add corner cases and problematic situations

Think about divisions by zero, out of bounds inputs, negative numbers, huge inputs

Don't start coding without a good understanding of the problem

7/10🧵

Please, know a little bit about the company you're applying to!!

You don't need to be a heavy user but at least know what their popular products do!

Bonus: If you could improve one of their products, what would it be?

8/10🧵

When I applied for the first time for Google, I had 14 years of experience but I didn't prepare enough

I failed and felt horrible for some months! This led to big changes (for the better) in my life and if you all want I can come back to this

9/10🧵

Summary:
• Practice
• Study the basics
• Practice
• Communicate
• Mock interview
