For example, if you’re applying for a role in the software engineering department and there's an urgent need for developers, the job interview process can be quite fast.

Below are the four stages of the job recruitment and interview process at IBM:

1. Application and Screening (Duration: 1-2 weeks): After you have completed an online job application form, wait for an email or call from IBMers to screen your submission.

2. Online Assessment (Duration: 1 hour and 40 minutes): This stage is an online assessment based on the role you applied for which lasts for 100 minutes.

IBM Interview Stages

Here’s a more detailed view of how IBM's interview process takes place.

Stage 1: Application

To get a job interview with IBM, you just have to fill out the application for the position you are interested in on the company's official website.

The online application form will require details such as educational background and work experience.

Make sure you prepare an impressive resume and portfolio to maximize your chances of moving on to the next stage of the hiring process.

IBM also suggests that you sign up for their talent network to receive relevant updates based on your expertise.

Stage 2: Screening

The IBM screening process takes place after you submit your online job application.

In this stage, your submitted application will be screened by a team of experts. If you pass the screening, you will receive either a call or an email on how to proceed.

Stage 3: Online Assessment

If you pass the preliminary screening, you must complete an online assessment.

You will complete several tests, depending on the role you’re applying for. The online assessment typically includes tests on cognitive ability, coding skills, video assessment, and English language assessments.

This entire assessment can last up to 100 minutes and there could be as many as 75 questions.

Stage 4: Final Interview

The IBM final interview consists of two parts: the Technical and HR interview.

During a technical interview, you might discuss topics like data structures and algorithms, operating systems, networking, system design, and programming languages. Each of these is geared to find out if you have the skills for the role.

To pass the Technical interviews, make sure you possess and hone the skills necessary for the position.

Similarly, the HR interview often aims to determine if you're a good fit for IBM's company culture. In this stage, you might be asked to share about your career aspirations and goals. Personality tests are often featured here.

The IBM final interviews could be done in person, over the phone, or via video call. You might also be invited to take the interview in one of IBM’s assessment centers. In that case, expect to participate in group exercises.

Stage 5: Decision / Offer

After your technical and HR interviews, the waiting time for the results takes around 2-4 weeks. But again, this depends on the current number of applications IBM receives at that particular moment.

If IBM decides to give you the job, it will provide the important documentation so you can start the onboarding process.

5 Essential Tips to Ace the IBM Interview Process

Learn all you can about IBM, including the company's core principles, programs, services, current initiatives, and the department or team you're hoping to join.

Knowing these things can help you respond to what the recruiters want to hear.

2. Practice and prepare for behavioral interview questions

IBM often uses behavioral questions to assess whether a candidate is suitable to work for the company.

Thus, take the time to review core concepts and the skills relevant to your field.

Be fully prepared to showcase your area of expertise and discuss how your previous work experiences can help you perform your role at the optimal level.

4. Practice mock IBM interviews

When you engage in mock interviews with other people, you prepare yourself to perform better in your actual IBM interview.

Moreover, mock interviews are also a useful tool for you to gain useful insights into what kind of questions you perform best and which ones you need to work on.
