Generally, tech interviews consist of a mix of behavioral and case interviews.
Note that case interviews are not like those in consulting: case interviews intend to uncover how you think and what your ideas are. There is not a specific structure that you need to adhere to — rather, hiring managers are attempting to evaluate you based on the quality and creativity of your ideas. Case questions themselves are aligned to your specific job function, focusing on how you would approach your function's day-to-day responsibilities.
*Note: it's likely to skip an interview with the recruiter if your background is well-suited to the role
Tech interviews will vary widely for company to company, so there is no "formula" for interviewing. Rather than memorizing several sets of questions, do your research on the company itself and really dive deep into what matters to the company: what does the future look like? Which business units/segments are likely to grow, and why? Are there any market factors to take into consideration? Who are the competitors to the company, and who are the competitors to the product?
"Look for hints in the job description. Companies will usually put which skills they're particularly looking for in there. For example, if the description says one responsibility will be to launch a campaign? Be prepared to explain how you would go about launching a campaign."
Skim the 10-K to understand how the company is structured and which areas of the company that leadership is invested in.
Talk to 2nd years (and peer advisors!) to understand what the interview format might be like. Alumni are also extremely helpful in uncovering the culture of a particular company.
When in doubt, apply early. Tech companies don't necessarily require a cover letter or referral. Some companies might care about this more than others, but overall, it's better to get your application in early than to stress about getting a cover letter and/or referral. The best thing you can do is to tailor your resume for the role you're applying to.
Express enthusiasm during your interview. Have a reason for why this company and role are aligned with your goals and interests. You would be surprise by the number of candidates who are ill-prepared in providing response for why they want to work at the company they applied for!
Breathe, and give yourself a break from recruiting every now and then. Recruiting can become an incredibly stressful process — so do whatever you can to take time for yourself and relax. Remember that you are worthy of the jobs you are applying for. Trust yourself and be confident in the skills you bring to the table. In moments of doubt, write down your strengths and repeat them back to yourself. You made it this far and are an incredible candidate: one company will see that and recognize that. It is a numbers game once you get to a final round interview, and it can often be a toss-up. You got this!
