First of all: there is no perfect “roadmap” for interviews. Every company, team, role, level, interviewer, and hiring process is different. Instead of memorizing answers, the better strategy is to understand what the role requires, prepare the fundamentals, and practice explaining your thinking clearly.
Before deep-diving into preparation, it is worth understanding which level you are applying for. Once you know the level, you can estimate what the company will probably expect from you.
| Career stage | Common titles | Typical expectations | Rough experience |
|---|---|---|---|
| Entry-level / Junior | Software Engineer I, Junior Software Engineer, Associate Software Engineer | Builds small tasks with guidance, learns team practices, focuses on fundamentals | 0–2 years |
| Mid-level | Software Engineer II, Backend Engineer, Full-stack Engineer | Owns well-scoped features, understands trade-offs, works with less supervision | 2–4 years |
| Strong mid-level / early senior | Software Engineer III, Senior Backend Engineer, Senior Software Engineer in some companies | Handles complex features, improves systems, mentors informally, thinks beyond one task | 3–6+ years |
| Senior | Senior Software Engineer, Lead Software Engineer in some companies | Owns larger technical areas, mentors others, makes design decisions, communicates trade-offs | 5–8+ years |
| Staff / Principal track | Staff Software Engineer, Principal Engineer, Senior Staff Engineer | Influences across teams, sets technical direction, identifies architectural risks, raises engineering quality | 7–10+ years |
| Distinguished / Fellow / higher | Distinguished Engineer, Fellow, Architect, company-level technical leader | Works on company-wide technical strategy, long-term architecture, and organization-level technical problems | 10+ years |
NOTE: This table shows approximate career stages, not universal company levels. Company leveling systems are different: for example, Google, Amazon, Meta, Microsoft, and startups can map titles and levels differently. Use this as a rough orientation, not as a strict rule.
Before preparing for the technical interview, you first need to get there: apply → recruiter notices you → recruiter sends an invitation for an initial screening or recruiter call.
To get there, you need to nail the basics: resume, profile, projects, communication, and positioning.
Congratulations! Being noticed by a recruiter is already a big deal, especially in the current market 🙂
Usually, recruiters want to understand two things:
If you are applying to an international company, their main concerns might be visa status, relocation cost, work authorization, tax setup, and bureaucracy. In short: they want to hire someone with fewer headaches.
During the recruiter call, the recruiter usually wants to learn about your previous experience and expectations: salary, benefits, notice period, visa situation, and other practical details.
Keep it short and clear. Mention what you worked on, your role, and the domains you have experience in, such as e-commerce, banking, infrastructure, logistics, SaaS, etc. Do not exaggerate too much 🙂
Do not go too deep unless they ask. For example, do not explain how B-trees work inside databases during a recruiter call. Just mention the main technologies you used: Go, Docker, PostgreSQL, Redis, Kafka, AWS, and so on.
