Make sure your LinkedIn profile is compete and updated
Don't approach yourself. See if you have any connection with a person who is working in that company, then request him to find an opportunity for you.
You can drop them a “Hi” and attach your CV for reference. All the best!
it doesn't leave a good impression
Internshala, Naukri are better in terms of finding internship/ jobs.... some have job offers after internship!!
Go introduce yourself, ask if they have any openings in the field you into and done..
Don’t connect directly. First text them . Hi , I hope you’re doing great. It is good to see we have some mutual . Hope to connect with you soon. Have a great day ! Thanks and then when they reply back them send the request. It is the best way to connect with someone .
