International Business Machines or IBM is a leading name in the information technology industry, and the company is most likely responsible for half of the technology we use today. 

With more than 380,000 employees, this technology and consulting business is considered to be among the best in the world for excellent employment practices. In addition to being the pioneer of technology, IBM is also one of the earliest adopters of Equal Employment Opportunity, Diversity, and Equal Pay in workplaces. The salary bands, employee benefits, and a great work-life balance are some other factors that contribute toward making IBM a highly sought-after employer.

IBM is a tough company to get into, and the competition is extremely stiff. Only with the right preparation strategy and perseverance can you nail the IBM interviews. The interview process for a software developer at IBM has several rounds that test the technical and behavioral skills of the candidate.

This article is a complete IBM interview process guide that’ll help you closely understand what the interview process at IBM entails and how you need to plan your preparation strategy if you want to crack the interview and land an opportunity to work as a software developer in the company.

Here’s what we’ll cover:

About IBM

Started in 1911 and headquartered in Armonk, New York, IBM is currently operational in 170 countries around the globe and is one of the largest employers in the world. The computer manufacturer was earlier known as Computing-Tabulating-Recording Company.

IBM’s services range from software development, system hardware manufacturing to infrastructure, hosting, cloud, and business consulting services. Also known as the Big Blue, IBM is one of the most reputed tech companies globally and is known for innovation. This is a primary reason why software developers are interested in working at IBM — for the opportunity to explore and grow are aplenty here.

The multinational tech company offers services spanning diverse industries, including healthcare, finance, education, telecommunication, and more. 

Eligibility Criteria to Apply for Jobs in IBM

Fresh IT graduates that wish to begin their career at IBM should have completed their bachelor's degree from a recognized university with a consistently good academic performance.

Experienced candidates will need to have a few years of experience in Software Design and should be well-versed in Data Structures, Algorithms, and relevant programming languages. The exact criteria will differ based on the role you’re applying to. If you meet the criteria mentioned, you can apply for the IBM interview on the company's career portal.

IBM Interview Approach

The IBM interviews are designed differently for fresh graduates and experienced candidates, and the expectations differ for each.

Fresh Graduates:

The IBM interview process tests grads in the following:

  • Cognitive ability
  • English language
  • Learning agility
  • Coding knowledge

Experienced Candidates:

The IBM interview process for experienced candidates is much more specialized and related to the domain of expertise. The process involves the following rounds:

  • Telephonic interview
  • Objective test of programming language
  • Logical reasoning
  • Technical interview
  • Behavioral interview

The interview process at IBM has a shorter timeline for experienced candidates than fresh grads or entry-level positions.

IBM Interview Process

Before you start your interview prep for IBM, familiarize yourself with all the interview rounds that the IBM interview process entails to help you create an effective preparation strategy. 

The IBM interview process involves the following steps.

  1. Application - In the first step, you must fill out the application for the position on the company's official website. You can also join their talent network to stay updated with the latest opportunities and stay connected with the company.
  2. Screening of the application - Your application is then screened by experts who decide if you should progress to the next round.
  3. Online assessment - The next step involves an online assessment of the candidate. This round may include one or more assessments depending on the role — Cognitive Ability Assessment, Coding Assessment, Video Assessment, and English Language Assessment. No role requires you to complete all four assessments.
  4. Interview/assessment center - If you clear the online assessments, you’ll be called for a personal interview which is further split into two rounds — Technical and HR.

Please note: Due to the ongoing pandemic, all rounds of interviews are conducted online.

The timeline of the interview process at IBM varies with the position and the interviewing panel. The onboarding can be extremely quick if the company is in urgent need of software engineers or developers. Generally, the interview process can extend up to two weeks or even more than a month. There is no fixed timeframe for receiving the offer letter from the company.

Once your application is shortlisted, there are basically two parts to the interview process. Let’s look at what each entails. 

Part 1 – Online Assessment

The online assessment at IBM consists of topics like Quantitative Aptitude, Number Series, and English language. There are 72 questions, and the duration of this test is 100 minutes. 

The English language test includes questions related to vocabulary, grammar, and comprehension. If you have a basic understanding of high school concepts, you can get through this round easily. The questions are multiple-choice and do not have any negative marking. 

Candidates who qualify for this round are called for an interview usually conducted at IBM assessment centers. This round can only be cracked if you have enough practice. 

Take up mock aptitude tests online to make sure you’re well prepared to get through this round. In addition, practice puzzles and other logical reasoning questions for this round. With a basic understanding of the concepts and time management skills, you can easily clear IBM’s online assessments.

Part 2 – Technical and HR Interview Rounds

Candidates who make the cut in the online assessments are usually invited onsite for technical and HR interview rounds. The Technical round at IBM is identical to FAANG companies (Facebook, Amazon, Apple, Netflix, and Google).

To clear IBM’s technical round, you must have a strong fundamental understanding of your domain subjects. The questions in the technical interview at IBM revolve around topics such as data structures and algorithms, DBMS, OOPs, networking, and system design

We’ll talk about how you can prepare for technical and HR rounds at IBM in the following sections.
