    FAE Interview

    Anonymous Interview Candidate in Boston, MA
    No Offer
    Negative Experience
    Difficult Interview


    I applied through other source. The process took 2 weeks. I interviewed at Littelfuse (Boston, MA) in January 2020.


    Brief and rude - I was contacted on LinkedIN from HR. I said I was interested but had a couple questions. HR told me they'd answer them after I sent a resume. They never did answer them. Several days later during work-day I get a call on my cell from the HR women. I was in a meeting so sent to VM. Called her back immediately after, she couldn't talk but she'd call me back in 30 minutes. 3 hours later she called, I politely answered, she said Oh I redialed the wrong number and started to hang up. I said, please wait, we were supposed to talk earlier. She said OK, we discussed why I was leaving my job. Then she asked my salary needs for a Boston based job. Keeping in mind she contacted me, my desired salary($150K) was way above what they could pay. So they want someone with 20 years experience but at a salary of 2 years experience.
