Where to apply

Ask for a referral to Ericsson

A referral only means something if the person giving it can actually speak to your work. I will refer you where I know someone on the inside and your profile genuinely fits the role, and I will tell you plainly when I cannot. Either way you get an answer, and a straight one.

  • I read every request. A reply takes a few days, sometimes longer.
  • I will not refer someone for a role their profile does not fit. It wastes your time and costs me the contact.
  • Where I cannot refer you, I will say why, and point you at the way in that does work.
  • Nothing you send here is shared with anyone without you agreeing to it first.

If you found the opening, paste it. It tells me which team you mean.

A Drive, Dropbox or personal-site link is fine. Make sure it opens without a request for access, or I cannot read it.

At least a short paragraph. This is what I would be putting my name behind, so specifics beat adjectives.

Comma separated, up to six. Things you would be happy to be tested on.

How they hire

Ericsson describes one process for all roles; the number of interviews and whether a case or assessment is included vary by position.

  1. 1

    Online application

    Official
    Application screen

    Create an account and submit the application, which Ericsson says takes a few minutes.

  2. 2

    Recruiter conversations

    Official
    Recruiter screenRemote

    One or two shorter phone or video calls, usually with the recruiter who stays with you through the process.

  3. 3

    Interviews with the hiring manager

    Official
    Hiring manager

    Between one and three interviews depending on the role, with the hiring manager or a senior management team. Virtual interviews run on Microsoft Teams.

  4. 4

    Case interview or assessment

    Official
    Technical interview

    Some positions include a case interview or assessment.

  5. 5

    Reference check

    Official
    Final HR round

    At the end of the process Ericsson asks for references and contacts them.

  6. 6

    Offer and contract

    Official
    Offer

    The final candidate receives a contract with the position offer and benefits package.

What comes up

Recurring themes from candidate accounts, not a question bank. Nobody is served by leaked question lists, least of all you in the interview.

  • Experience against the role requirements

    Official

    Be ready to explain how your experience matches the requirements in the job ad.

  • Examples from past work

    Official

    Interviewers like to hear concrete situations you have been in and what you learned from them.

  • Curiosity about Ericsson technology

    Official

    Ericsson suggests learning about its work, such as 5G or AI in networks, and bringing your own questions.

LetsDefend

What it pays

Nothing collected for this company yet, and nothing worth guessing at. A made-up range is worse than no range because people negotiate against it.

Add to the Ericsson page

This library is only as good as what people who have been through it are willing to share. Most of these companies have no hiring process documented anywhere, and one account of what the rounds actually were is worth more than anything I can research from the outside.

What are you adding?

This decides how the claim is labelled on the page. Only someone representing the company can produce an “official” label, and I check that separately.

Year and month.

Comma separated topics, not the questions themselves.

Round by round is ideal: what each one was, how long, remote or in person, and what it covered.


Credit

Anonymous is the default. If you keep it anonymous, nothing identifying you reaches the page: it is published as a candidate account and your name stays with me. Never send anything covered by an NDA, and never send a take-home or a question paper.

Universities they recruit from

No sourced university links yet. A campus drive, a career fair appearance or an internship partnership is what puts a university here.

How to actually get seen

Want me to refer you here?

Send me the role, your CV and a few honest paragraphs on why you fit it. Where I know someone inside and your profile matches, I will make the introduction. Where I cannot, I will tell you why and point you at the route that does work. You get an answer either way.
