Should I accept an offer at Mastercard or at Capital One for Software Engineer Intern?

For reference, I was from the suburbs of St. Louis growing up and I currently have 2 offers.

If I stay in St. Louis with Mastercard, I heard I am almost guaranteed a return offer and I wont need to pay rent in the near future. The salary is significantly lower but still very good according to levels.fyi

If I accepted an offer at Capital One I also heard I am almost guaranteed to get a return offer however, I would need to relocate, pay rent, and move from family. The entry-level salary is definitely enticing according to levels.fyi

Based on this information, do you think I should stay in St. Louis?

I also had a few additional questions:

How easy is it to get back into Mastercard by applying through their new grad opening if I end up doing C1 instead?

How long does it take to get promoted to Senior SWE at Mastercard on average?

Can a dual tower CPU cooler break a MSI motherboard during car transit?

Can a dual tower CPU cooler break a MSI board during car transit? I feel less concerned about the GPU since it is secured directly into the case using the mounts on the back. But the CPU cooler is mounted directly onto the board, putting a lot of stress on that area.

Optimal Google SWE Internship location

I am applying to Google SWE internship for summer 2027, and I really want to optimize my chances of getting in.

What should I select as my #1 preferred location? Does anyone have any metrics on acceptance rates / cultures between different offices? I feel like the HQ office will hire the most interns, but it might not be the most optimal for getting in since everyone is gonna select this office as their preferred location.

How to optimize your response to "How did you hear about us" on job/internship applications

Usually, I am honest when answering this question and I usually just put Linkedin or Handshake. But I am having second thoughts about whether its possible to optimize this part of my application as well.

I feel like recruiters would want you to have learned about their company through career event or some kind of in person event rather than linkedin. Or at least through their company website.

Does anyone here know if this question can be optimized or not? And if so, can you give me a rating scale for what is the best and worst answers to write here?

Also, if I write campus event, will recruiters ask about it during an interview? Cause if they ask then I would be cooked.

How to optimize a resume for Mastercard SWE Intern

The Job Description of Mastercard SWE intern seems pretty broad to me. They want someone who has:

• Basic understanding of programming languages such as Java, Python, C++, JavaScript, or similar
• Strong foundation in data structures, algorithms, and core computer science concepts
• Familiarity with version control (e.g., Git)
• Interest in software testing, debugging, and problem solving
• Curiosity, motivation, and a willingness to learn

It seems like this is pretty basic stuff that every CS major has.

I am unsure how to optimize my resume for this. When I applied to other companies, I usually try to keyword match and tech-stack match. But I am unsure of which technologies to list for the Mastercard SWE Intern role. Could someone enlighten me on what they really want to see in a candidate?

Also, for future reference, how in-depth do they go about your projects? I learned that they focus more on projects than on DSA for their interview (usually only LeetCode easy), but do they expect you to explain at a high level or will they pull up a random file from your GitHub and ask you to explain architectural design decisions / grill you on the details of specific frameworks you listed on your resume?

Pls help; I really want to work for Mastercard since they pay the best for SWE, and their office is in my hometown, so if given the role, I could spend another summer at home!

Now that companies are starting to move more towards asking both leetcode and large codebase debugging, how are we supposed to prepare?

I ain't sure how to prepare for codebase debugging questions. Is there a standardized place for me to get these kinds of questions to practice?

Regular leetcode is pretty straightforward; just practice on leetcode and try to memorize the patterns, then apply them to new questions. Are there patterns to large codebase debugging, and where do we go to learn the frameworks for these questions?

WTF is the point of filling out a job application form if everything is already on your resume, and also why cant these ATS companies just remember what u put on previous applications and autofill?

I recently filled out a internship application for this company, and in one of their form fields they wrote:

"Please do not indicate “See Resume”."

WTF is the point of uploading a resume then? The company is just gonna force you to fill in all the fields again in their proprietary ATS software.

Also, why can't ATS software like Workday just keep track of my previous responses to all of these questions, then autofill it for new job applications? I have probably filled out over 500 Workday forms in my 2 years of job hunting, and boy would it have saved me a shit ton of time and sanity if Workday would just remember my citizenship status, skills, age, veteran status, disability status, pronouns, gender, race, graduation date, GPA, work history, skills, travel percentage, languages, degree, etc.

Amazon RDS instances can't be that expensive, especially for a company that is already profiting from my data.

HYS vs SPAXX as a cash reserve for credit card autopay?

I am currently using a regular checking account as a cash reserve for credit card autopay, but I dont want this cash reserve to just sit there and lose value over time.

Looking around at this sub, I see people are getting 4%+ interest on their HYS, while SPAXX only gets around 3.3%. The only issue is that a lot of savings accounts restrict payments, while the Fidelity CMA automatically converts SPAXX into cash when you make a payment.

Do you folks recommend HYS or SPAXX? And if you recommend HYS, could you suggest an account for my use case with no payment fees, minimum balance, yearly account fees, etc.?

How reliable is fidelity CMA + SPAXX as a credit card autopay setup?

I am thinking of using Fidelity CMA with SPAXX as my main cash account so I can simplify my banking setup and put checking, savings, and everything in between into one account that both gains interest and can be easily liquidated.

I plan to make all my purchases with credit cards for cashback, but I plan to autopay the full statement balances using the CMA, since Fidelity claims they will automatically convert SPAXX into cash whenever you pay from their CMA. But I am wondering how reliable this type of setup is. Has anyone ever encountered a SPAXX liquidation glitch that caused them to go into late payments?

Furthermore, how safe is it to keep all of my cash in SPAXX, given that the value could fluctuate? If anyone is using this kind of setup or has used this kind of setup, I would appreciate it if you could tell me all of the caveats and whether this setup is actually better than just using a checking account for autopay while still being safe enough!

Prompt 2: Tell us about a piece of Palantir coverage or content you find thought-provoking and why.

I lowkey applied because of the company's tech-like culture, but I need to come up with something super unique to wow my recruiter. Would you folks be able to suggest some ideas?

Is there any mcq or knowledge-based questions?

What are some companies that sponsor a TS/SCI clearance for interns

I was trying to apply to Palantir FDE, but a lot of those positions require you to already have a TS clearance.

I currently only hold a mid-level FR clearance from Peraton (not related to defense/government), so I am automatically DQ'd from applying. However, I want to try again next year. It seems that not many interns at this stage would be able to even get a clearance in the first place, so if I were to have a TS, I would have a very good chance of getting that internship next semester.

Thus, could someone compile a list of companies that sponsor TS clearance for interns? Leidos is the only company I know that is willing to sponsor TS for intern positions.

Also, it may be useful to mention that I am a second-generation Chinese American (US-born citizen), so I am unsure if my family connections in China might make me ineligible for clearance in the first place.

Is it just me or does SWE recruiting starting to care more about which high school you went to this recruiting cycle?

I remember Palantir asked about which high school I went to in their SWE intern application for 2026, and so I wasn't surprised when I saw that question again this year. However, I have been seeing more and more companies ask this question for 2027 SWE internship applications. HRT, for example.

Why do companies care so much about high school now, and is recruiting trending towards hiring from target high schools as well now? If so, is there anything we can do to maximize our chances?

Should you select all the locations for preferred location on a SWE internship application form?

When applying to SWE internships, we are all used to the "preferred location" question. But to maximize our chances, should we be selecting all of the available locations, or should we choose only a few of the locations?

I feel like it could go both ways, since if you select all the locations, you could get a better chance for a human to look at your resume. But on the other hand, selecting all of the locations makes you look desperate and (possibly) reduce your ATS score.

Can some recruiter enlighten me about this?

Also, is this more of a universal answer or does the answer depend on the ATS brand (Workday, ICIMS, Greenhouse) or custom ATS configuration?

The Google SWE intern application is already out in July, but I thought it usually comes out in September. Nvidia, Anduril, Salesforce - all of them are already out.

I am applying to these 2027 internships before my 2026 internship is even over. Should I apply right now, or should I wait it out and see if I can get some better bullet points on my resume from my current internship?
