Hi everyone,

I have gone through ServiceNow Administration and HRSD, and now I want to move toward ServiceNow Development.

I would like to get some guidance from experienced ServiceNow professionals about the skills I should focus on to become job-ready.

  • Do I need to learn the complete JavaScript language, or are there specific JavaScript concepts that are more important for ServiceNow development?
  • What technical and ServiceNow-specific skills should I learn to apply for a ServiceNow Developer role?
  • If I want to apply specifically for an HRSD Developer role, are there any additional skills or HRSD-related areas I should learn?
  • Apart from ServiceNow Administration, HRSD, and Development, are there any other technologies, tools, or concepts that are expected from a fresher/junior ServiceNow Developer?
  • What would be the best learning roadmap from my current level to becoming job-ready?

I would really appreciate it if experienced developers could share their advice on what skills are must-have for getting a ServiceNow Developer or HRSD Developer job and what can be learned later.

Thanks in advance for your guidance!

Hello @anjalinegi1 ,

 

Welcome to servicenow community 😀

 .

You can start with practicing in Servicenow PDI .  

 

When you start exploring ServiceNow PDI, begin with understanding the basic platform UI:

  • Application Navigator, Banner, Content Frame (UI16)

  • Explore Forms and List Views

  • Company Branding and changing the Welcome Page

  • Context Menu (what it is and its types)

  • Breadcrumbs and how they work

Next, move on to data modeling basics:

  • Table and Field creation

  • Table dependencies and Table Extensions

  • Field types

  • Views

  • Important OOTB tables like User (sys_user), Group (sys_user_group), Role (sys_user_role), Delegations

Once you are comfortable with this, explore core configuration concepts:

  • Reference Qualifiers

  • Dot-walking

  • UI Policies

  • Dictionary Overrides

  • ACLs

  • Priority Lookup

  • Difference between Configuration vs Customization

Then understand data movement and backup concepts:

  • Update Sets (how to take backup of your work)

  • Update Set transfer methods

  • Import Sets

After learning these basics, you can confidently move forward to explore Service Management modules like:

  • Incident

  • Problem

  • Change

  • Request

And then deep dive into the Development part.

 

CSA is the basic and most important certification for ServiceNow beginners

Main topics to focus on:

  • Platform UI and navigation

  • Tables, fields, forms, and list views

  • Users, groups, and roles

  • Basic ITSM concepts

  • UI Policies, Client Scripts, and Business Rules (basic understanding)

Best practices:

  • Practice each topic in your Personal Developer Instance (PDI)

  • Do not just memorize answers—try to understand why a feature is used and when to use it

Once you follow this path, your ServiceNow learning journey will be smooth and structured 

 

 

Try to spend 2-3 hours daily  on community which will help you understand different real  time scenarios ,different approaches . Explore University Course which also enhance your knowledge.

Start with the "Welcome to ServiceNow " training, it's really good and it will gives you your first certificate!

The Certified System Administrator (CSA) certificate is initial stage , it's useful for almost for any servicenow role .
