Do you have any advice on how to get a job at Nokia?

I would recommend to highlight international job & study experiences as much as possible. There's no shortcut to recruitment in a company this size - so you need to follow the official career channels and make your application stand out as much as possible. Think about enhancing your application with some digital aids

Hi Diaa,
Thank you for your inquiry.
It's awesome that you are interested in a career at Nokia.
As a first step, please apply for the Nokia open position(s) at:

Of course, there are no guarantees of employment. After applying for the position(s) that you feel are right for you, and assuming the hiring manager chooses to interview you for the position, here are a few time-tested interviewing tips that you might find helpful. (1) Interviewing is stressful, so it is important to stay calm, confident, attentive, and enthusiastic throughout the interview. (2) Prepare for the interview by not only being able to describe, discuss, and respond to questions about the job-related skills and qualifications reflected in your resume, but also by researching the company. (3) If in-person or via video conferencing, wear business-appropriate attire for the interview. (4) Be on time, better to be a few minutes early, for your interview. (5) Keep good posture, and maintain eye contact with the interviewer, and take a few moments, if needed, to think before answering the interviewer’s questions. (6) Be prepared to discuss how your own knowledge, skills, attitudes, behaviors, and experiences match the company’s job requirements. (7) Follow-up shortly after the interview with a thank-you note to reemphasize your sincere interest in the position, and as an opportunity to share any relevant information you may have omitted during the interview.

Project self-confidence, stay positive, and concisely communicate and sharing examples of the knowledge, skills, attitudes, behaviors, and other qualifications that make YOU the best candidate for the job you want.
