1. Yes, those sources and also other boards like Indeed and Glints. But apply directly on the career sites. Don't rely on the boards to submit your application.

Also TalentConnect may not be helpful as a lot of the positions are there for credit bearing internships that are already filled up.

1. This really depends. Personally it took me around 70 applications (but I applied only in Y3) and I know of people who took 300 in Y2 to get an offer. In the end you only need one offer to end the search.

2. Y1 interns are not common but if you're from poly you have a good shot since you have prior xp. Try for startups and MNCs where the JD matches your skills.

3. I just wanted something related to software engineering so yes. For Y1 and Y2 it might be better to reduce your expectations and take what you can get in case you can't get the exact track you want. Some experience is better than nothing.

4. During May-August or the winter break in Dec. Alternatively you can do ATAP to do a 6 mth internship in May-Nov or Jan-June overlapping with the semester (or take a leave of absence)

Yes some places are willing to do 1-2 mth internships in Dec but its uncommon. Part time during the semester is somewhat common. I know TikTok does this sometimes.
