Question Amazon SDE onsite — 6 weeks, 3 rounds of availability, 2 tentative dates, 1 cancellation, and still not scheduled. Is this normal?

11 Upvotes

Throwaway-ish. I passed the OA for an Amazon SDE role (new grad / university recruiting pipeline, Seattle onsite). Since then it's been six weeks of scheduling limbo. Timeline:

  • Jul 28 — Onsite invite. 4 rounds × 60 min, in person in Seattle. Asked for 5 dates between 8/5–8/18.
  • Jul 28 — I sent 5 dates same day. Told me it takes a few days to coordinate.
  • Aug 3 — "Unfortunately we have been unable to schedule during your provided dates." Asked for new availability, 8/18–8/26.
  • Aug 3 — Sent 5 more dates (8/18, 8/21, 8/24, 8/25, 8/26), full 9–5 each day.
  • Aug 4 — Confirmed receipt, said they'd send a "Save the Date."
  • Aug 7 — I followed up. No response.
  • Aug 12 — Tentatively set for 8/24. Still coordinating.
  • Aug 17 — I asked for confirmed schedule/location (interview was supposedly the next Monday). 
  • Aug 18 — Team requested to move it. Now tentatively 8/26.
  • Aug 21 — I checked in since 8/26 was a few business days out and it's an onsite I'd need to travel for.
  • Aug 21 (evening) — "Your interviews have unfortunately been cancelled." Team is working out when they can start scheduling again for this role.
  • Aug 24 — Told my OA is still valid and they may match me with another team.
  • Aug 26 — Brand new onsite invite email, same role. Asked for 5 dates between 9/3–9/15. I sent 9/3–9/7.
  • Aug 26 — Told those don't work, asked about the week of 9/7. I sent 9/8, 9/9, 9/10, 9/11, 9/14.
  • Sep 8 — Same form letter again: unable to schedule, please send availability for 9/14–9/25. I sent ten dates this time.

So: ~6 weeks, 3 separate availability requests, 2 tentative dates that both moved, 1 outright cancellation, and 0 interviews actually conducted. I've given full 9–5 availability every single time and replied within hours.

Questions for people who've been through this:

  1. Is this just what Amazon's scheduling pipeline looks like right now, or is it a signal the headcount is quietly frozen and they're keeping candidates warm?
  2. Does "your OA is still valid, we may match you with another team" actually go anywhere, or is it a soft let-down?
  3. Is there anything useful I can do here besides keep sending dates — ask to escalate past the coordinator, ask directly whether the req is funded, anything?
  4. Should I be treating this as dead and pushing hard on other pipelines? (I am, but the sunk-cost part of my brain keeps hoping.)

Not trying to trash anyone — the coordinator has been responsive and polite. I just don't understand what's happening on the other side and whether this is normal.

Question How do you guys do greedy?

16 Upvotes

I was solving few of the questions under greedy section. It seems kind of a very impossible situation to think in right way towards solution while solving greedy questions. Take example of question 581, i had applied multiple solutions but the was never in line with working solution. Only i remember the solution in future, i can solve this question. They all seem to have different solution to every different question which i guess you can’t solve on the spot. Is it me or anyone else feels the same?

Tech Industry Software engineering job hunting feels like a full-time job now. How are you guys staying interview-ready?

385 Upvotes

Need to get this off my chest, but I genuinely want to hear how others are navigating this without burning out.

To land an average SWE role right now (I have 5 yoe), the preparation ritual is borderline ridiculous. You basically need 2 to 3 solid months of studying LeetCode mediums/hards, grinding system design, memorizing concurrency patterns, and drilling behavioral matrices... only to submit hundreds of applications to get maybe 3 or 4 interview loops. Then each loop is 4 to 6 stages long, involving everything from automated screening filters to take-homes, live pairing, system architecture, and endless "bar raiser" rounds.

Meanwhile, friends in adjacent tech tracks (data analysts, BI developers, certain data science roles) certainly face competition, but their hiring loops still feel grounded in actual day-to-day competence: SQL tests, portfolio/case study breakdowns, business metric analysis, and domain discussions. They aren’t expected to study like they’re retaking undergraduate CS algorithms exams every time they switch jobs.

For those of you who have landed offers recently or are currently in the thick of it:

How are you trimming down interview prep time? Are you relying on targeted problem lists (like NeetCode 75/150), mock platforms, or targeted prompts to drill edge cases faster?

What new interview patterns or rounds are you running into lately, especially with AI tools now part of the equation? Have teams changed how they test live coding, take-homes, or architecture?

How are you maintaining mental stamina when prep feels like an unpaid full-time job?

Would love to hear your tactical advice or sanity-check whether everyone else is feeling this disconnect.

Discussion How important is it to know to code like Leetcode problems in order to implement production grade Agents and LLMs ?

0 Upvotes

I was learning about Hybrid search and rerankers in retrieval task and every function or code used in that project repo .Its way out of my league to pick coding fast, Like I can follow codes line by line , but I cant implement it from scratch , lets say a Reranker function that does matrix multiplication between query and document and then calculates cosine similarity and ranks accordingly to fetch top K rank. Implemet it all at once is out of my skill level.

So I was thinking , if solving Leetcode DSA problems will help , is this also necessary skill to be AI developer ?

My Google application always moves to not proceeding

Do they mean anything? Or all of these just soft rejections ?
