We did not advise or help any of our kids with job/internship searches. Ours were all involved in professional clubs at school which provided a lot of resources as well as being in certain professional academies at their schools.
However, if they needed our help we would have done so, they are all very much self starters and good networkers.
Would never have spoken to a hiring manager on their behalf. I’ve had parents reach out to me for help with a contact and I always say, your kid should be doing the reaching out - it’s their career.
So, good to be helpful but let the kid do the actual work.
