Interview Process for Cloud Engineer Role

The general interview process for a cloud engineer role is quite straightforward. 

Most interview questions are based on security, services, and procedures, which you can solve if you have some basic cloud engineering skills.

The interview process usually starts with easy to medium-level questions. 

You should start your interview preparation journey knowing more about Array, Lists, Stacks, and Binary Trees, and establish at the interview time that you have a sound knowledge of DSA.

Normally, the interview process is divided into four main sections:

✅ Aptitude: This section tests your ability in mathematical aptitude, logical reasoning, and general reasoning. Most of the questions are of easy to moderate difficulty level.

✅ Operating Systems: Here, you need to share your knowledge of operating systems, including memory management, process lifecycle, contiguous memory, and process tables. This section is of a moderate difficulty level.

✅ Coding: Under this section, you require proving your theoretical as well as practical skills. You must have a decent level of coding skills under your belt.

✅ Analytical And Troubleshooting Skills: You will be tested on how you interact with instances and have to establish your troubleshooting and problem-solving skills. Analyzing things and getting to a result from a log file is an important attribute that comes under cloud engineer roles and responsibilities.

In addition to the above, cloud engineer requirements include that a candidate has good communication skills. 

They must be able to make an effective channel between the working team and all the stakeholders. 

This ensures that a cloud engineer can share the most time-efficient solution when an incident occurs.

Interview Preparation Strategy for Cloud Engineer

You can start your interview preparation by researching the common cloud architectural patterns and techniques they work on. 

The best way is to familiarize yourself with the three-tier architecture pattern, as it is most popular among various companies. 

You should consider learning the appropriate cloud services that can be applied to a particular type of architecture.

Apart from having a general knowledge of cloud computing, you must have a basic knowledge of different platforms like AWS, Azure, IBM, Red Hat, etc. 

Understand the features of various platforms and know the problems they can tackle.

If you are looking for more opportunities, focus on the market leader. 

And in the case of cloud engineering, AWS is the leader, so prepare your interview in accordance with this platform.

Regardless of the job position you are applying for, find the common practices in your line. 

Once you know them, go into deep details, along with the techniques you can use. 

In case there are specific technologies needed in your job, focus on them. 

This will help when your current practical experience is insufficient, but you will still be capable of explaining the concepts in general overview.

Most of the time, an interviewer will test you with the adaptability of your cloud technology knowledge rather than your in-depth knowledge of a particular cloud platform.

You can also start your interview preparation with a project development report on cloud computing.

This will help you establish that you are experienced in cloud-based tech and have a firm grasp of SaaS technologies, platforms, and applications. 

Your working project can also reveal that you have an intimate knowledge to customise cloud computing attributes to a business effectively.

Interview Preparation Tips - Cloud Engineering Skills to Have

There are several tips to help you get your cloud engineer interview right.

The interviewer is most likely to ask debugging questions, including situational questions. 

It helps test the hands-on knowledge of a candidate and tells the interviewer the way a candidate will implement things in a given situation. 

This is the strategy where the recruiter understands that you are comfortable with a long-time or a short-time solution.

➡️ Practice Scripting, Python, and Golang and understand layers of networking.

➡️ Learn Mind Mapping trick. It will help you to explore every topic in detail and let you answer anything the interviewer may raise on your way.

➡️ Get yourself enough time to go into interview mode. If you are a working professional, ask the recruiter for more time to help prepare yourself with the interview topics.

➡️ Make a schedule and stick to it. Create a timeline goal and calculate the time you want to spend for preparation, considering your current job.

➡️ Categorize your topics according to weekdays and weekends. As you will have less time on weekdays, choose the points that need less time to grasp. Likewise, on weekends, work on the conceptual elements that need more time.

➡️ Prepare your topics according to the desired role you are applying for, that is cloud computing.

➡️ Make sure you find the skills that are needed and restructure them.

➡️ Take help from a mentor, as they can share the right resources. They can also help you with the best interview preparations through a series of mock interviews. They will also discuss the weaknesses you need to work on and the areas where you need to focus on during the interview.

➡️ Prepare yourself for the specific cloud engineer role. It is easier to go through the interview when you are well prepared with the technologies and the specifications that a particular role is demanding.

Recruiters usually prefer experienced candidates for the post of cloud engineer. But freshers are not kept away.

It will surely help showcase you as a desirable candidate for the post.

Common Mistakes to avoid during Interview Preparation

There are some most common mistakes mentees make during interview preparation.

🔶 Sticking to a Single Resource

Never stick to one resource during your interview preparation. For example, most candidates rely upon gathering information online. 

The Internet is a good source of information, but most of the content there is generic and may not fit your particular situation.

🔶 Failing to Consult a Recruiter or Mentor

An open-ended conversation with your mentor can be paramount in your interview preparation.

They have already gone through the interview process, so they can find the right resources to help you.

Moreover, they can tell you the topics you can expect at the time of your interview.

🔶 Not Practising Questions Online

One of the most common modes of interview preparation is mugging up the sample questions online. 

You might go through a series of sample questions, but there are fair chances that at the interview time, the first question you are asked is far away from what you have learnt online.  

Certifications and your Job Interview

Certificates are just for your interview purpose, and after that, your knowledge will get you through.

Your knowledge is the key and can never be compromised. 

If you can showcase your working knowledge, then certificates are merely added qualifications. 

However, certain roles require a certificate as an eligibility criterion, but in most of the job roles for cloud engineers, they are not the only way.

Many service-based companies prefer having certification. 

You can consider earning a relevant certificate to help showcase your knowledge and skills. 

Some of the most popular certifications include:

🟢 AWS Certification

Here you can choose from Cloud Practitioner, Solutions Architect, Developer, SAP on AWS, and SysOps Administrator.

🟢 Google Cloud Platform Certifications

It includes Professional Cloud Architect, Professional Cloud Developer, and Professional Cloud Security Engineer certifications.

🟢 Microsoft Certifications

Here, you can opt for Azure Developer or Azure Fundamentals.

There are two types of certifications: vendor-neutral and vendor-specific.

Vendor-neutral typically covers all general concepts very well. 

But, if you want to start working on actual projects, then a vendor-specific foundation-level certification from a platform like AWS, Microsoft Azure, or Google Cloud can be a better option.
