1. Application & Screening: After you apply online, your resume is reviewed by a recruiter. If your qualifications match the role, the recruiter may reach out for an initial phone interview.

2. Recruiter Call: The recruiter will discuss your background, skills, and the job role in detail. You may be asked about your experience with system architecture, your technical skills, and your motivation for applying to Intel.

3. Technical Interview: This stage may include multiple rounds, either conducted over the phone or via video conference. You may be asked to solve technical problems related to system design, architecture principles, software and hardware interaction, scalability, and performance optimization.

You might also face questions about your experience with various tools and technologies related to system architecture, such as cloud computing, microservices, distributed systems, and design patterns.

Expect whiteboard or coding exercises that require you to demonstrate problem-solving and analytical skills in real-time.

1. Behavioral Interview: This round assesses how well you fit within Intel's culture and values. Questions will often focus on how you've handled complex projects, worked in teams, and managed stakeholders. The goal is to understand your leadership, collaboration, and communication skills.

Example questions: "Tell me about a time you faced a challenging system design problem and how you resolved it?" or "Describe a situation where you had to work under pressure."

1. On-Site Interview (or Final Virtual Interview): If applicable, you may be invited for an on-site interview (or a final video interview). This may include additional technical tests, discussions with senior architects or team members, and deeper dives into your past projects and experiences.

The interviewers will likely assess both your technical and problem-solving skills in depth, along with your ability to communicate complex technical concepts clearly.

1. Final Discussion with Hiring Manager: You may meet with the hiring manager to discuss the role in more detail, expectations, team dynamics, and the specific challenges of the position. This is often the final step before an offer is extended.

2. Offer & Negotiation: If you successfully pass the interview process, you will receive an offer. This stage might include discussions on salary, benefits, and other compensation details.

HashMap: A HashMap is a part of the Java Collections Framework and is used to store key-value pairs. It doesn't guarantee any specific order of the elements.

It is implemented using a hash table and provides constant-time performance for basic operations like adding, removing, and accessing elements (assuming the hash function disperses elements properly).
