With the world going more and more digital every day, digital transformation for businesses is no more optional. Isn’t it? When new technologies like big data, machine learning, cloud computing, AI are flourishing and emerging, any organization would think it is stupid enough not to use them. And that is why they are hiring Digital Transformation Officers like anything. A Digital Transformation officer is someone who bridges the gap between organizational growth and digital transformation by determining how the business could accelerate with the help of technologies.
It seems like a pretty interesting job. Isn’t it? But, if you want to get into it, you need to know a lot of things. Because you see, it’s not just one technology like any regular job profile, it’s a mixture of all the emerging technologies altogether. Now, once you sit for the interview for a digital transformation officer, that means you need to know 5 basic skills in the following fields:
Now, let’s check out the most asked interview questions on these 5 technologies that are any interviewer’s favorite:
Ans. Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. The term is generally used to describe data centers available to many users over the Internet. Large clouds, predominant today, often have functions distributed over multiple locations from central servers. If the connection to the user is relatively close, it may be designated an edge server.
Ans. The benefits of cloud computing are mentioned below:
Ans: A cloud is a combination of networks, hardware, services, storage, and interfaces that helps in delivering computing as a service. It has three users :
Ans. The different data types used in cloud computing are emails, contracts, images, blogs, etc. As we know that data is increasing day by day. so it is needed for new data types to store these new data.
Ans. The different layers that define cloud architect is:
Ans. A home network is basically a test environment. How you work with it gives an indication of what you would do with someone else’s network.
Ans. A threat is a possible danger that might exploit a vulnerability to breach security and therefore cause possible harm.
Vulnerability refers to a flaw in a system that can leave it open to attack.
Cybersecurity risk is the probability of exposure or loss resulting from a cyber-attack or data breach on your organization.
Ans. Ping is a layer-3 protocol like IP; ports are an element of the layer-4 protocols TCP and UDP.v
Ans. SSL is a standard security technology for creating an encrypted link between a server and a client (usually a web server and a web browser).
Ans. HTTPS is a hypertext transfer protocol and secures communications over a network. TLS is transport layer security and is a successor protocol to SSL. You have to demonstrate that you know the differences between the three and how network-related protocols are used to understand the inherent risks involved.
Ans. Supervised machine learning requires training labeled data.
Whereas, Unsupervised Machine Learning doesn’t require it.
Ans. Bias is an error introduced in your model due to the oversimplification of the machine learning algorithm.
Variance is an error introduced in your model due to the complex machine learning algorithm, your model learns noise also from the training data set and performs badly on the test data set.
Ans. Exploding gradients are problems where large error gradients accumulate and result in very large updates to neural network model weights during training.
Ans. The confusion matrix is a 2X2 table that contains 4 outputs given by the binary classifier. Error-rate, accuracy, specificity, sensitivity, precision, and recall can be derived from it.
Ans. Selection bias takes place when the sample obtained is not representative of the population intended to be analyzed.
Answer: A scrum script takes 3-4 weeks to complete. On average, the duration of a scrum sprint is 4 weeks.
Answer: Velocity is the rate at which the team progresses sprint by sprint.
Answer: Impediments are the obstacles or issues faced by the scrum team which slow down their speed of work. If something is trying to block the scrum team from reaching their goal then it is an impediment. Impediments can come in any form. Some of the impediments are:
Answer: Agile is a methodology used for project management.
On the other hand, Scrum is just a form of Agile that describes the process and its steps more concisely.
Agile and Scrum both involve completing projects in steps or incrementally and is iterative in nature.
Answer: An increment is the total of all the product backlogs items completed during a sprint. Each increment includes all the previous sprint increment values as it is cumulative. It must be in the available mode in the subsequent release as it is a step to reach your goal.
DevOps is a term used in the IT industry which promotes collaboration and communication between software development and operations team to streamline the process of software delivery with a minimum failure rate of releases. It also helps to speed up the delivery, optimize automation of processes and improvise through quick feedbacks.
You are suggested to have a clear knowledge of agile methodology.
There are many industries that are using DevOps in order to minimize the time deadline risks, mitigation of bug fixes, better working relationships, quality delivery of software and taking care of customer satisfaction. Moreover, it reduces costs and increases the chances of succeeding companies. The primary objective of DevOps is to help us to get the production processes as quickly as possible while minimizing the risks in software quality assurance and compliance.
Agile is a methodology that focuses on the development of software. It aims to establish continuous delivery, shorten feedback loops and improve team collaboration through the software development life cycle (SDLC).
Lean IT is a methodology that focuses on eliminating unwanted processes that add no value and it aims to streamline the value stream of the product development cycle.
DevOps which consists of Dev – development & Ops – operations focuses on both processes of the product. For smooth and automated processes, it allows us to effectively unite the roles between automation tools and IT professionals.
If you have work experience in the past then you can mention how it helped in your previous job. Otherwise, you can explain it as below :
Technical Benefits :
Business Benefits :
Three most common DevOps KPIs are:
